(x2 - y2)/(x - y) = (x + y)(x - y)/(x - y) = x + y
it is (x-y)(x-y) :)
Only when X or Y = 0 That is because (x + y) squared = x^2 + 2xy + y^2 x^2 + 2xy + y^2 = x^2 + y^2 when x or y = 0
X + y
Y squared (Y^2)
The factoring is as follows: x2 - y2 = (x + y) * (x - y)
The GCF is xy
(x+y)2
-1
multiply by 2y/x
2
5(x^2 + y)
