Question

For all which value(s) of x will the rational expression below equal zero? Check all that apply

Answer 1

ASolution

Given

`((x-1)(x+5))/(x-5)`

When the rational expression is zero , we have

`\begin{gathered} ((x-1)(x+5))/(x-5)=0 \\ \\ (x-1)(x+5)=0*(x-5) \\ (x-1)(x+5)=0 \\ x-1=0\text{ }or\text{ }x+5=0 \\ x=1\text{ or }x=-5 \end{gathered}`

The correct choices are E and F
