How To: Multiply rational expressions

Multiply rational expressions

The video describes the basic process of multiplying two rational expressions. The problem illustrated in this video involved multiplying rational expressions of monomial terms with integer coefficients. As with the other example problems, we follow the steps of: factoring, canceling, and multiplying. Because these terms are monomials, no factoring is required (but we still state it as a step for similarity to solving other problems). We then find the greatest common divisor for both terms to cancel as much as possible. We finalize the process multiplying the remaining terms and and dividing the variable terms. By following the three easy steps, a problem that initially appeared hard can be reduced in a very manageable and pragmatic way.
