Multiplying Rational Expressions
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.
