Question

Simplify the rational expressions. State any excluded values. X^2-4/2-x

Answer 1

Answer:

-x-2;  x$\neq$2

Step-by-step explanation:

$\frac{x^2-4}{2-x}$-->

$\frac{(x-2)(x+2)}{(2-x)}$ -->

-(x+2); x CAN'T equal 2, because the denominator of the original fraction would be 0, which would make the term undefined.
