x^2-1/x^2-x-2 - x-1/x-2
The question is unclear. Is it
.
%28x%5E2%29-%281%2Fx%5E2%29-x-2-x-%281%2Fx%29-2
-OR-
%28%28x%5E2-1%29%2F%28x%5E2-x-2%29%29-%28%28x-1%29%2F%28x-2%29%29
or something else entirely?
The second above is easiest, but if that is not it, please re-post more clearly
.
%28%28x%5E2-1%29%2F%28x%5E2-x-2%29%29-%28%28x-1%29%2F%28x-2%29%29
%28%28x%2B1%29%28x-1%29%29%2F%28%28x%2B1%29%28x-2%29%29-%28%28x-1%29%2F%28x-2%29%29(x+1) divides out
%28x-1%29%2F%28x-2%29-%28x-1%29%2F%28x-2%29=0
ANSWER: Choice B is correct.
