for what value of x is the rational expression below equal to zero? 2-x/2+x
Answered by Damon
(2-x)/(2+x) maybe?
if x = 2, numerator is zero, expression is zero

if x = -2 Explodes, undefined
Answered by Henry
(2-x)/(2+x).
A fraction is equal to zero only when the numerator equals zero:

2-x = 0, X = 2.
