9.2 Multiplying and Dividing Rational Expressions
Multiply x + 1 by 3 to find the numerator of the product, and multiply x ­ 1 by 2(x + 1) to find the denominator. Then cancel common factors to simplify the product.

9.2 Multiplying and Dividing Rational Expressions
When finding excluded values of a product of two rational expressions, find the values of x for which the denominator of either expression is 0. When finding excluded values when dividing one rational expression by another, find the values of x for which the denominator of either expression or the numerator of the second expression is 0.
When dividing rational expressions, find the reciprocal of the divisor and change the division problem to a multiplication problem. Then follow the steps for multiplying rational expressions.
