Four review homework assignments: These are each worth 15 points, vs. the usual homework assignment of 4 points.
Unit 1 review homework (Chapters 1, 2, 3).
Due last Thursday.
Unit 2 review homework (Chapters 4, 5, 8):
Due today.(If you need an extension on either the Unit 1 or 2 Review, see or email me TODAY so you can finish it and get access to the Unit 3 review HW.)
Unit 3 review homework (Chapter 6):
NOTE: You must get at least 80% on the Unit 2 Review before you can start the Unit 3 review. Due at the start of class tomorrow (Tuesday, May 7)
Unit 4 review homework (Chapter 7):
NOTE: You must get at least 80% on the Unit 3 Review before you can start the Unit 4 review. Due at the 8:00 p.mon Study Day (Wed., May 8)
Room 203
Jarvis Hall Science Wing
Regular hours through Tuesday, May 7 (8 AM – 6:30 PM)
Finals Week Open Lab Hours:
Starting at 10 a.m. on Study Day (Wed.) and 8 a.m. on Final Exam days

CLOSE
YOUR LAPTOPS,
and turn off and put away your cell phones,
and get out your notetaking materials.
Unit 3 Covers:Chapter 6 (Rational expressions)
Don’t forget to review the application problems from section 6.6 homework and your work on the offline worksheet.
(Remember those fun problems about planes and cars, and three people doing a job at different rates?)
These were a common source of trouble for many students in previous semesters, so make sure you study the application problems on the Practice Test, and then review the section 6.6 homework if you need more work on those problems.
Unit 3:Chapter 6 (Rational Expressions)
Almost all problems in Chapter 6 on rational expressions require you to use one or more techniques for factoring polynomials.
DON’T FORGET TO REVIEW THESE FACTORING METHODS AND KNOW HOW AND WHEN TO USE EACH ONE!
Two methods that students often have trouble with are factoring by grouping and sums/differences of cubes, so make sure you review problems using these methods.
Find the domain of the expression
Solution: Set the denominator equal to zero and solve for x. (Notice that this boils down to a factoring problem.)
x2 – x – 20 = 0
(x – 5)(x + 4) = 0
(x – 5) = 0 gives x = 5,
and (x + 4) = 0 gives x = 4
Therefore the domain is {x  x ≠ 5 and x ≠ 4}
Multiply the following rational expressions.
Solution: Factor each polynomial completely,
then cancel all factors that appear on both the top
and the bottom.
NOTE: This problem uses factoring by grouping, factoring out a GCF (twice!), and the sum of cubes formula.
Whew!
Add the following rational expressions.
Dividing a polynomial by a monomial:
Divide each term of the polynomial separately by the monomial.

35
x

15
Dividing a trinomial by a binomial:
Divide 7x into 28x2.
Multiply 4x times 7x+3.
Subtract 28x2 + 12x from 28x2 – 23x.
Bring down 15.
Divide 7x into –35x.
Multiply 5 times 7x+3.
Subtract –35x–15 from –35x–15.
Nothing to bring down.
So our answer is 4x – 5.
HOW WOULD YOU CHECK THIS ANSWER???
Example of a complex fraction:
10
3x .
5
6x
Solution: view as a division problem:
10÷ 5 = 10 · 6x = 4
3x 6x 3x 5
Solve 2x + 1 = 1 .
2x – 1 x 2x – 1
Solution:
1. Multiply both sides by the LCD x(2x – 1).
This gives 2x(x) + 1(2x – 1) = 1(x)
2. Now simplify this equation:
2x2 + 2x – 1 = x
2x2 + x – 1 = 0
3. Solve either by factoring or by using the quadratic formula.
Answers: x = 1, x = 1/2
NOW CHECKBOTH ANSWERS in original equation:
Note that when you plug in x = 1, everything checks out OK ( you get 1/3 = 1/3)
BUT when you plug in x = 1/2, you get zeroes in some denominators, so this number is NOT a solution. (it gives 1 + 1 = 1
0 ½ 0
So the final answer is just x = 1
(if you write x = 1, 1/2, you’ll get ZERO credit.)
REMINDER: Comprehensive Practice Final:
Once you finish the Unit 3 and 4 Final Review homework assignments with at least an 80% score, you will have access to the practice final, with as many attempts as you want.
The practice final is worth 10 points, plus a possible bonus of up to 20 extra credit points on the final exam. Your best percentage score on the practice final will earn that percent of 10 points toward your course grade, plus that best score percent times 20 extra credit points will be added on to your final exam point score before partial credit points are added.
This makes it extremely important for you to make sure you work to get at least 80% on each of the four final exam review homework assignments so that you can get access to the practice final.
