5%2F%282x%5E2%29+-+3%2F%28x%5E2%2B2x%29+%2B+2%2F%28x%5E2-4%29
To start, we to get rid of the denominator by multiply by a common factor, in this case, x^2+2x-4:

Cancel out leaving:
5%2A%282x-4%29%2F2+-+3%2A%28-4%29+%2B+2%282x%29
Then simplify:
%2810x-20%29%2F2+%2B12+%2B4x
5x+-+10+%2B+12+%2B4x
9x%2B2
