    your answer is 5x-10y use difference of squares to simplify into: \[(5x+10y)(5x-10y)\div(5x+10y)\] (5x+10y) crosses out from the equation because \[(5x+10y)\div(5x+10y)=1\] so you are left with 5x-10y

    it should be, you are looking for a quotient, right? so if 6 is divided by 3, the quotient is 2
