Best ResponseYou've already chosen the best response.0Did you try factoring out the x and y? If it helps, try rearranging the terms like so: \[x^2  2x  y^2 + 2y\] and try grouping/factoring the x out and the y out

Best ResponseYou've already chosen the best response.1x^2  y^2  2x + 2y (x^2  y^2) + (  2x + 2y) (x  y)(x + y) + (  2x + 2y) (x  y)(x + y)  2( x  y) See where to go from here?
