Francesco3 · Accepted Answer

3(x-y)• (x + 1) - (x + y)•(x - y) + 4 •(x - y)^2  (x - y)• [ 3•(x + 1) - x - y + 4•(x - y) ]   (x - y)•( 3x + 3 - x - y + 4x - 4y)   (x - y)•( 6x - 5y + 3)

EidosM · Answer

3(x-y) (x + 1) - (x + y)(x - y) + 4 (x - y)^2 = = (x - y) [ 3(x + 1) - x - y + 4(x - y) ] = = (x - y)( 3x + 3 - x - y + 4x - 4y) = = (x - y)( 6x - 5y + 3)
