I have assumed that the problem is meant to look like.
%284-2x%29%2F%28x2-12x%2B20%29
Factorise the top and bottom parts of the problem.
2%282-x%29%2F%28%28x-2%29%28x-10%29%29 Take a factor of -1 from the (2-x) to get -1(x-2)
-2%28x-2%29%2F%28%28x-2%29%28x-10%29%29 Cancel the (x-2) term on the top and bottom of the fraction
-2%2F%28x-10%29
