Review Algebra

Section R.1 Polynomials

Your Turn 1 Solution: Multiply each polynomial by the coefficient in front of the polynomial and then combine like terms.

Your Turn 2 Solution : Using the Distributive property yields

Section R.2 Factoring

Your Turn 1 Solution: Each of these terms is divisible by 2z2.

Example 4

Section R.3 Rational Expressions

Your Turn 1 Solution: Factor both numerator and denominator in order to identify any common factors. The answer can not be further simplified.

Your Turn 2 Solution: Factor where possible.

Section R.4 Equations

Your Turn 1

Your Turn 2

Your Turn 3 Continued

Your Turn 4 Continued

Your Turn 4 continued

Section R.5 Inequalities

Your Turn 1

Section R.6 Exponents

Your Turn Solution:

Section R.7 Radicals

Your Turn Solution: The best approach here is to multiply both numerator and denominator by √x + √y . The expressions √x + √y and √x − √y are conjugates, and their product is
