To solve a rational expression start by simplifying the expression by finding a common factor in the numerator and denominator and canceling it out. Then, check for extraneous solutions, which are values of the variable that makes the denominator equal to zero.

Answer: When x = − 3, the value of the rational expression is 0; when x = 4, the value of the rational expression is − 7; and when x = 5, the value of the rational expression is undefined. This example illustrates that variables are restricted to values that do not make the denominator equal to 0.

We can summarize the process as follows: Factor the numerator, factor the denominator, identify factors that are common to the numerator and denominator, cancel them to represent division, and simplify.
