Substitute directly into the function. Simplify the expression.

%282%28x%29%5E2%2B3x-7-%282a%5E2%2B3a-7%29%29%2F%28x-a%29

%282x%5E2%2B3x-7-2a%5E2-3a%2B7%29%2F%28x-a%29

%282x%5E2%2B3x-3a-2a%5E2%29%2F%28x-a%29
This is as far as you can go. Performing the division will not give you anything better, but you can try it.
