It is: 2(x+4) when factored
2(x+4)
8
4(x^2 + 2x + 8)
xy plus 2x plus 4y plus 8 or (xy+2x) + (4y+8) or x(y+2) + 4(y+2) or (x+4)(y+2)
-x2 + 2x + 48 = (-x - 6)(x - 8) = -(x + 6)(x - 8)
(2x - 1)(5x + 8)
(7x - 8)(2x - 7)
(2x - 1)(x + 2)(x^2 - 2x + 4)
(x + 4)(y - 2)
(x + 4)(y - 2)
(x + 4)(y - 2)
(x+4)(x-2)
