%288x%5E2+%2B+11xy+-+17y%5E2%29+%2B+%282x%5E2+%2B+4xy+-+18y%5E2%29+ Start with the given expression.


8x%5E2%2B11xy-17y%5E2%2B2x%5E2%2B4xy-18y%5E2 Remove the parenthesis.


%288x%5E2%2B2x%5E2%29%2B%2811xy%2B4xy%29%2B%28-17y%5E2-18y%5E2%29 Group like terms


10x%5E2%2B15xy-35y%5E2 Combine like terms


So %288x%5E2+%2B+11xy+-+17y%5E2%29+%2B+%282x%5E2+%2B+4xy+-+18y%5E2%29+=10x%5E2%2B15xy-35y%5E2
