Question 965572
.
x^2-1/x^2-x-2 - x-1/x-2 
The question is unclear. Is it
.
{{{(x^2)-(1/x^2)-x-2-x-(1/x)-2}}} 
-OR-
{{{((x^2-1)/(x^2-x-2))-((x-1)/(x-2))}}}
or something else entirely?
The second above is easiest, but if that is not it, please re-post more clearly
.
{{{((x^2-1)/(x^2-x-2))-((x-1)/(x-2))}}}
{{{((x+1)(x-1))/((x+1)(x-2))-((x-1)/(x-2))}}}(x+1) divides out 
{{{(x-1)/(x-2)-(x-1)/(x-2)=0}}}
ANSWER: Choice B is correct.
