(x+1)(x-1)/(x+1)squared
-------
[(x+1)(x-1)]/[(x+1)(x+1)]
--------------
Cancel the common (x+1) factor to get:
(x-1)/(x+1)

Are we simplifying the expression?
If so, we have: %28x%2B1%29%28x-1%29%2F%28x%2B1%29%5E2
Recall, with like bases we can subtract exponents if we are dividing.
So, this becomes %28x%2B1%29%5E%281-2%29+%2A+%28x-1%29+=+%28x%2B1%29%5E-1+%2A%28x-1%29
To simplify, we cannot have negative exponents, so we have to make everything in terms of positive exponents. Recall that a^-1 = 1/a. So (x+1)^-1 = 1/(x+1).
Thus our final answer is : %28x-1%29%2F%28x%2B1%29
