1. Section 2: Multiplying and Dividing Rational Expressions

2. SSimplify rational expressions. MMultiply and divide rational expressions.

3. rrational expression

4. YYou can simplify rational expressions to determine the probability of hitting an archery target. ((See Exercise 35.)

5. IIn Lesson 8-1, you worked with inverse variation functions such as y = 5/x. TThe expression on the right side of this equation is a rational expression. AA rational expression is a quotient of two polynomials. OOther examples of rational expressions include the following:

6. BBecause rational expressions are ratios of polynomials, you can simplify them the same way as you simplify fractions. RRecall that to write a fraction in simplest form, you can divide out common factors in the numerator and denominator.

9. YYou can multiply rational expressions the same way that you multiply fractions.

11. YYou can also divide rational expressions. RRecall that to divide by a fraction, you multiply by its reciprocal.
