SOLVE
Assume the expression is:
%28x%5E2-y%5E2%29%2F%28z-x%29 where x=-3, y=5, and z=-1
Just substitute the given values for the variables
%28-3%5E2-5%5E2%29%2F%28-1-%28-3%29%29
minus a minus, is a plus, minus times a minus is plus also
%28-3%5E2-%28-5%5E2%29%29%2F%28-1%2B3%29 = %289-%28%2B25%29%29%2F%282%29 = %28-16%29%2F2 = -8
