    Did 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

    Actually i tried that and it doesnt work... grouping doesnt work... Completing the square doesnt work...

    x^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?

    @jim_thompson5910 started you off great. There is still something in common you could factor out to further simplify it. Think about it
