Homework Assignments
 These are listed in chronological order.
 Note: "EOO" (every other odd) means to do problems
1, 5, 9, 13, 17, 21, 25, 29, 33, 37, 41, 45, 49, 53, 57, 61, etc.  Note: Please do "E.C." (extra credit) problems on a separate sheet of paper from the regular assignment. These are due at the next exam.
 These are tentative; the instructor may make changes to this list from time to time. Due dates will be announced in class.
 Students must not rely on printed versions of this list; instead, they should check the live online version periodically for possible updates.
 Students who work ahead and complete one or more assignments in advance are taking a risk that the assignment(s) may change before the due date, in which case the advice in the preceding sentence is particularly applicable.
 Students should not expect to earn extra credit for completing tentatively assigned exercises that are later modified or removed from this list.

5.7  Polynomial Equations and Their Applications  1–45 ODD  — 
6.1  Rational Expressions and Functions: Multiplying and Dividing  1–15 ODD (for #7 through #15, the domain consists of all real numbers such that the denominator is not zero); 27–87 EOO (if you need extra practice, you may optionally try the remaining ODD problems from 29–89)  — 
6.2  Adding and Subtracting Rational Expressions 
1–65 EOO (if you need extra practice, you may optionally try the remaining ODD problems from 3–63) Recall that (1) all subtracted numerators must be parenthesized when they are combined over a single denominator, and (2) canceling is not legal if either term has a plus/minus sign near it. Recipe: (0) Are denominators all the same? If so, skip to (5). (1) Factor all denominators which are not prime; parenthesize prime denominators. Make a fraction out of any term which is not already a fraction; for example, convert $8$ into $\frac{8}{1}$. (2) Multiply any fraction containing a "reversed" denominator with a subtraction (example: $(yx)$ when there is an $(xy)$ in another denominator) by $\frac{1}{1}$. (3) Find the LCD by playing "who has the most" with the denominators, and write it down. (4) Multiply each fraction by the necessary $\frac{\text{fudge factor}}{\text{fudge factor}}$ to create matching LCDs in each denominator. (Do not reduce fractions at this stage!) (5) Parenthesize each numerator and combine (while retaining the parentheses) into a single numerator over the LCD. (6) "FOIL", distribute, simplify, and combine like terms in the numerator, then factor the numerator if possible; copy the denominator as empty parentheses at each step. (Never "FOIL" the denominator.) (7) If possible (usually it isn't), cancel matching factors in the numerator and denominator; write remaining answer in full.

6.3  Complex Rational Expressions  (No assignment)  — 
6.4  Division of Polynomials 
1–11 ODD  — 
6.5  Synthetic Division and the Remainder Theorem  (No assignment)  — 
6.6  Rational Equations 
1–33 ODD Recipe: (1) Factor all denominators which are not prime; parenthesize prime denominators. Make a fraction out of any term which is not already a fraction; for example, convert $x$ into $\frac{x}{1}$. (2) Multiply any fraction containing a "reversed" denominator with a subtraction (example: $(yx)$ when there is an $(xy)$ in another denominator) by $\frac{1}{1}$. (3) Find the LCD by playing "who has the most" with the denominators, and write it down. (4) Multiply every term or fraction in the equation by $\frac{\text{LCD}}{1}$, but do not FOIL or distribute anything. (5) Cancel all matching pairs of factors in the numerator and denominator; only cancel factors with a multiplication symbol (possibly an invisible one) next to them. (6) All denominators should be 1 and disappear, but if they are not, return to step (1) and repeat. (7) FOIL or distribute everything, then combine like terms. (8) If the result is linear, solve the equation by isolating the variable. If the result is a polynomial equation (quadratic or higher), then isolate a zero on one side of the equation, then solve by factoring the nonzero side. (9) (REQUIRED) Substitute each candidate solution into the original equation to verify. Discard any candidate solutions which cause any denominator to become zero. Box the remaining solutions or, if none remain, indicate that the solution is the empty set $\varnothing$.

6.7  Formulas and Applications of Rational Equations 
1–13 ODD Recipe: (1) Follow steps (1) through (7) from the recipe in section 6.6. (2) Using addition or subtraction ONLY, move any term containing the "FOR" variable to the left side of the equation, and any term not containing the "FOR" variable to the right side of the equation. (3) If there is more than one occurrence of the "FOR" variable on the left side of the equation, factor the left side into a distributive with the "FOR" variable in front. If there is only one occurrence of the "FOR" variable on the left side, then continue to the next step. (4) Divide both sides of the equation by whatever factors remain on the left side of the equation other than the "FOR" variable. This should isolate the "FOR" variable to complete the problem. You do not have to check formula problems.

7.6  Radical Equations  1–37 EOO  44; 46 
7.7  Complex Numbers  1–91 ODD  — 
8.1  The Square Root Property and Completing the Square 
1–61 EOO Recipe for completing the square: (0) If the problem is an expression, write it in the form $y=ax^2 + bx + c$; if it is an equation, write it in the form $0=ax^2 + bx + c$. (1) Add or subtract the $c$ term as needed to remove it from the right side of the equation (it will show up next to $y$ or the $0$ on the left). (2) Divide the entire equation (each term) by $a$; if there is a negative in front of the $x^2$ term, multiply or divide each term by $1$. This step may create fractions; do not be alarmed. (3a) In the margin, multiply the coefficient of the $x$ term (last term on the right) by $\frac{1}{2}$ and call the result $h$ (for "half"); make a note of it. (3b) In the margin, square $h$ (that is, find the value of $h^2$) and write it also. (4) Return to the main calculation and add $h^2$ to both sides of the equation (simply append "$+ h^2$" to the other terms already present). (5) Concurrently simplify the left side as needed (this may require using an LCD), and factor the right side into a perfect square of the form $\left(x + h\right)^2$. The value of $h$ from step (3a) will always be the number next to the $x$ inside the parentheses (it's mathemagical). (6) If the original problem was an expression, then isolate $y$ on the left side by adding or subtracting a term (if needed) and then clearing fractions (if needed), in that order. If the original problem was an equation, then take the square root of both sides of the equation (always insert a $\pm$), and take additional steps as needed to isolate $x$. In either case, never "FOIL" or distribute the parentheses from step (5).

8.2  The Quadratic Formula 
1–53 EOO Recall that the "discriminant" is given by the value of the expression ${b^2}  4ac$. Never use the quadratic formula until the equation is free of parentheses and there is a zero on one side of the equation. 
— 
9.1  Exponential Functions  1–11 ODD; 17–23 ODD  — 
9.3  Logarithmic Functions 
1–19 ODD (use the rearrangement mechanism with the understanding that $b^n=p$ is equivalent to ${\log _b}n=p$); 21–41 ODD (hang "$=x$" onto the right side of the equation, then solve using the rearrangement mechanism); 53–71 ODD (use the properties summarized on the bottom of page 698 of the textbook, or try the rearrangement mechanism); Recall that $\ln x$ is always equivalent to ${\log _e}x$; convert all radicals to fractional powers before working any logarithm problem 
— 
9.4  Properties of Logarithms 
1–35 ODD (an expanded answer contains no products, quotients, radicals, or exponents); 37–59 ODD (a condensed answer contains no plus or minus signs and no coefficients, and "log" or "ln" appears no more than one time); 61–67 ODD (use the changeofbase formula and your calculator to obtain a decimal approximation rounded to the nearest tenthousandth)

Will You Succeed or Fail in Mathematics?
This checklist is adapted from a handout prepared by math and philosophy instructor Steve Thomassin. It will allow you to compare your approach to a mathematics course to the approaches taken by successful … and unsuccessful … students.
Attribute Type  Predictor of Success  Predictor of Failure 

Attitude  Focus on things that are under your control.  Blame things that are out of your control (the text, the instructor, or "the system") for your difficulties. 
Be optimistic. Believe that you can do it.  Be pessimistic. Convince yourself that you will fail.  
Be positive. Find ways to make math interesting and fun.  Be negative. Find ways to make math dull and painful.  
Be open. See the uses, power, patterns, and magic of mathematics.  Be closed. Blind yourself to math's uses and its practical and esthetic value.  
Be practical. Make yourself aware of the doors that passing each math class opens to you.  Be impractical. Ignore the doors that open when you pass a math class.  
Class Work  Attend every class. Aim for perfect attendance, even if you already know it all.  Be absent often. Dig a hole so deep that you cannot climb out except by dropping the course. 
Be focused. Concentrate on the math topic at hand.  Be mentally elsewhere. Daydream. Talk. Distract and annoy neighboring students.  
Take good notes. Solve problems along with the instructor.  Avoid participating in the discussion. Just watch the instructor.  
Be inquisitive. Ask questions so that the instructor knows what you would like to learn more about.  Be uninterested. Make the instructor guess what it is that you might be confused about.  
Homework  Be regular. Always do at least some homework before the next class, and finish by the due date.  Be sporadic. Do homework only when it easily fits your schedule. 
Invest time. Spend double to triple the amount of inclass time.  Invest little time. Spend less time doing homework than you spend in class.  
Review notes; read text; do all assigned problems (maybe even more), and check the answers.  Ignore notes and text explanations; try a few problems, and don't bother checking to see if they are right.  
Getting Help  When needed, take advantage of all opportunities: study groups, tutors, instructor office hours.  Even when lost, never seek assistance.
