8yz4
Simplify:
We will begin by writing the numerator and denominator in factored form. Then we will remove any factors common to the numerator and denominator.
The rational expression is simplified when the numerator and denominator have no common factors other than 1.
To simplify these expressions, we factor each numerator and denominator and remove common factors.
