What is a Rational Expression?

Steps to Simplify a Rational Expression 1.Factor the numerator and denominator completely. 2.Review the denominator to identify any excluded values (i.e., any values that would cause the denominator to equal 0). 3.Cross out any factors common to both the numerator and the denominator. (Make sure you understand why you can do this. You can only cancel factors, not terms!)
