(a + x^2)(b + y^2)
it is (x-y)(x-y) :)
(x + y)(x + y)(x + y)
It is then x/y when simplified
It is a quadratic expression in the variables x and y.
(x+y)2
(x2 - y2)/(x - y) = (x + y)(x - y)/(x - y) = x + y
(a + x^2)(b + y^2)
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)(x + y)(x + y)
It is then x/y when simplified
It is a quadratic expression in the variables x and y.

(3x + 3y)(x + y) = 3(x + y)2
