Question 1050542: please simplify the indicated operation
-8/(x^2-1) - 7/(1-x^2)

Here, -7/(1-x^2) is multiplied by (-1)/(-1) which doesn't change it
Now it is 7/(x^2-1). These have common denominators, so they may be added
The answer is -1/(x^2-1) OR 1/(1-x^2), doing everything in reverse. Both are acceptable answers.
