This document discusses how to simplify rational expressions by factoring and canceling like terms. It provides examples of multiplying and dividing rational expressions, showing that when multiplying you multiply the numerators and denominators, and when dividing you invert the second fraction and multiply. Restrictions are placed on variables to avoid division by zero, such as requiring variables not equal 0 when factoring or canceling terms.
