Rational Expressions 2: Multiplying and dividing rational expressions

Beginning with an introduction on multiplying fractions, this lesson first focuses on factoring out terms in the numerators and denominators of polynomial fractions.

In division, the same method is employed, but with a poignant reminder that when dividing fractions, including polynomial ones, one must reciprocate the second term.
