(x+y)2
(a + x^2)(b + y^2)
(3x - y+ 2)(3x + y + 2)
X + y
9y cubed plus 2y squared
it is (x-y)(x-y) :)
Oh, dude, y squared plus y squared equals 2y squared. It's like adding two of the same things together, you know? So, if you have y squared and add another y squared, you end up with 2y squared. Math can be pretty chill sometimes, huh?

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

(3x + 3y)(x + y) = 3(x + y)2
(y + 8)(y - 7)
