Question

For what value of x is the rational expression below equal to zero?2 - x------2 + xA. 0B. -1C. -2D. 2

Answer 1

D. 2

Step-by-step explanation

We have to find the value of x such that the rational expression is equal to zero.

`(2-x)/(2+x)`

This rational expression will be equal to zero when the numerator of the expression is equal to 0.

This means that:

`\begin{gathered} 2-x=0 \\ \text{Solve for x:} \\ x=2 \end{gathered}`

The answer is option D.
