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
All you can do to factor that expression is to divide both terms by y: y2 + 4y = y(y + 4)
(2, -2)
x2 + y2 = (x + iy)(x - iy) ' i ' = sqrt(-1) K2KQU
it is (x-y)(x-y) :)
(a + x^2)(b + y^2)
X + Y (X + Y) ^2 = (X+Y)(X+Y) Factor = (X + Y)
(x + y)(x + y)(x + y)
C2x + C2y = C2(x + y)
(3x + 3y)(x + y) = 3(x + y)2
4(x+y)^2
x2y + axy + abx + a2b Factor by grouping. xy(x + a) + ab(x + a) (xy + ab)(x + a)
3xy + 3y2 = 3y (x + y)
(x+y)2
