+%28%28x%5E2%2B10x-11%29%2F%28x%5E2-1%29%29++++%2A+++%28%28x%2B1%29%2F%28x%2B11%29%29+
Factor the numerator and denominator of the first fraction

Multiply straight across
+%28%28x-1%29%28x%2B11%29%28x%2B1%29+%2F%28x-1%29%28x%2B1%29%28x%2B11%29%29+
Notice the numerator is the same as the denominator.
Anything divided by itself equals 1
