%284x%2F2x%5E2%29%2Bx-10-%289x%2Fx%5E2%29%2Bx-6 Simplify the parentheses by canceling 2x in the 1st set and x in the second set.
%282%2Fx%29%2Bx-10-%289%2Fx%29%2Bx-6 Now put the terms over the common denominator of x.
%282%2Bx%5E2-10x-9%2Bx%5E2-6x%29%2Fx Simplify.
%282x%5E2-16x-7%29%2Fx or 2x-16-7%2Fx
