Multiplying and Dividing Rational Expressions

1. Multiplying and dividing rational expressions is similar to multiplying
and dividing fractions.

2. Multiply Rational Expressions: Multiply their numerators and
multiply their denominators. If and are rational expressions,
then

3. To write the result in lowest terms, factor each numerator and each
denominator before you multiply and divide out common factors.
Then multiply. (The answer is often left in factored form.)

4. Dividing Rational Expressions: To divide two rational expressions,
multiply the first rational expression by the reciprocal of the second.
That is, if and are rational expressions and   then

Be sure to cancel common factors after you have found the reciprocal
of the second rational expression.
