%28x%5E2-13x%2B42%29%2F%28x%5E2-36%29. Here you have to factorise both the denominator and the numerator. By doing so, you get

%28%28x-6%29%28x-7%29%29%2F%28%28x%2B6%29%28x-6%29%29 = %28cross%28%28x-6%29%29%28x-7%29%29%2F%28%28x%2B6%29cross%28%28x-6%29%29%29 = %28x-7%29%2F%28x%2B6%29 Answer.

Is this clear to you now? Pls let me know.
