Assume the problem is:
x%2F%28x%5E2-16%29 - 4%2F%28x%5E2%2B+5x+%2B+4%29
Factor the denominators
x%2F%28%28x-4%29%28x%2B4%29%29 - 4%2F%28%28x%2B4%29%28x%2B1%29%29
the common denominator: (x-4)(x+4)(x+1)
:
%28x%28x%2B1%29+-+4%28x-4%29%29%2F%28%28x-4%29%28x%2B4%29%28x%2B1%29%29 = %28x%5E2%2Bx-4x%2B16%29%2F%28%28x-4%29%28x%2B4%29%28x%2B1%29%29 = %28x%5E2-3x%2B16%29%2F%28%28x-4%29%28x%2B4%29%28x%2B1%29%29; about all you can do with it
