Oh, dude, you're hitting me with some math now? Okay, like, y squared plus y is technically y(y+1). So, like, if you're ever at a party and someone asks you that, you can just drop that knowledge bomb and impress everyone.
(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) :)
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
35
15
(3x + 3y)(x + y) = 3(x + y)2
(y + 8)(y - 7)
It is a quadratic expression in the variables x and y.
