(a + x^2)(b + y^2)
(3x - y+ 2)(3x + y + 2)
it is (x-y)(x-y) :)
15
(3x + 3y)(x + y) = 3(x + y)2
(a + x^2)(b + y^2)
(x+y)2
(3x - y+ 2)(3x + y + 2)
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

it is (x-y)(x-y) :)
15
(3x + 3y)(x + y) = 3(x + y)2
4(x+y)^2
x+y
y^2 + 7y + 12 = (y+4)(y+3)
