Multiply: x-6 x x+7/x^2-36
:
Assume you mean:
(x-6) * %28%28x%2B7%29%29%2F%28%28x%5E2+-+36%29%29
:
Note that x^2 - 36) is the difference of squares, so factor that:
(x-6) * %28%28x%2B7%29%29%2F%28%28x%2B6%29%28x-6%29%29
:
Now we can cancel out the (x-6)'s, we have:
%28%28x%2B7%29%29%2F%28%28x%2B6%29%29
:
