Answer :

ANSWER

D. 2

EXPLANATION

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

[tex]\frac{2-x}{2+x}[/tex]

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

This means that:

[tex]\begin{gathered} 2-x=0 \\ \text{Solve for x:} \\ x=2 \end{gathered}[/tex]

The answer is option D.
