Chapter 6 -- Rational Expressions and Equations

6.1 Simplifying Rational Expressions
Notice: you have two tasks to do - find the restrictions and simplify.
1 - 5, 8, 9, 13 - 17, 19, 20
Note - on problems 8, 13 - 15, & 17 you will factor out a (-1) as shown in Example 4 (a) and (b) - read the paragraph above Example 4 on page 264 and look over that whole example carefully. This is a very important skill.

6.2 Multiplying and Dividing Rational Expressions
2, 3, 6, 7, 10 - 12, 15 - 17, 19, 20

6.3 Adding and Subtracting Rational Expressions
1 - 5, 9 - 13, 17 - 21, 24, 25, 29, 31 - 33, 36

6.4 Solving Rational Equations
Note: there is a big difference between adding/subtracting rational expressions (no equal sign) and solving a rational equation (has an equal sign). Be sure you can keep the problems straight. Review the comparison on page 286.
1, 2, 5 - 7, 12, 13, 15 - 19, 22, 24, 26, 27, 31 - 33

Chapter 7 -- Square Roots and Radicals

7.1 Introduction to Square Roots
1 - 8 (be sure you understand the difference between exact form and approximate form), 9 - 15, 19, 20 (notice if you are finding the principal root, the negative root, or both), 21 - 32 (study Example 3 on pages 316 - 317 for a discussion on replacement values)

7.2 Multiply and Divide Square Roots
1, 3, 4, 7 - 11, 13 - 18, 19 - 24, 25 - 30, 32, 33, 36 - 43, 49, 50

7.3 Addition and Subtraction of Square Roots
Notice it is necessary to have like terms before adding or subtracting.
1 - 5, 9 - 13, 16 - 18, 23, 28, 30

7.4 Solving Equations with Square Roots
There are two types of problems here; pay attention to the difference. In the first type, the variable is not under the square root symbol. In the second type, the variable IS under the square root symbol. If the variable was originally under a square root symbol you MUST check your answer(s) in the original equation.
1 - 17, 20, 22

7.5 Using Square Roots
Memorize the Pythagorean Theorem; it will not be given on the exam. The distance formula and quadratic formula WILL be given on the exam if needed.
