You can put this solution on YOUR website!
Can you put parenthesis around the numerators of your fractions? It's hard to tell where one fraction ends and one begins.
------------------------------------
I'll give it a try. Please correct me if I'm not using the correct fraction.
%28z%5E2%2B11z%29%2F%28z%5E2-2z%29+%2B+%28z%5E2-8z%29%2F%28z%5E2-2z%29
We have the same denominator, so we can add numerators.
%28z%5E2%2B11z+%2B+z%5E2+-8z%29%2F%28z%5E2-2z%29

Yes, you are correct. Good job :)
