In this lesson you will learn how to Multiply Rational Expressions. By covering the procedure and making sure to cancel before multiplication and how to deal with expressions containing polynomials, you will be ready to tackle the last four examples at the end of the lecture.
To multiply two
rational expressions, first factor all the numerators and
denominators. Then cancel the common factors. Combine the
remaining factors to form the final, simplified answer.
If two factors in
the numerator and denominator look almost the same, factor 1 out
of either of the factors and see if you get two identical factors.
