(x - 2)(x - 4)
If that's 2x2, the answer is (x + 2)(x2 + 4)
(x-8)(x+8) = x2-64
x2-64 = (x-8)(x+8) when factored
x2+5x-24=0(x+8)(x-3)=0x=-8 x=3
x2 + 6x + 8 =(x + 2)(x +4)
-x2 + 6x + 16 = -(x2 - 6x - 16) = -(x - 8)(x + 2) = -(8 - x)(x + 2)
16 + 6x - x2 = 16 + 8x - 2x - x2 = 8*(2 + x) - x*(2 + x) = (8 - x)*(2 + x)
4x+8
(X + 2)(X + 4) Factored
x2 + 2x - 48 = x2 + 8x - 6x - 48 = x(x + 8) - 6(x + 8) = (x - 6)(x + 8)
The quadratic expression x2+6x+8 when factorised equals (x+2)(x+4)
(x - 2)(x - 4)
(-3,-1)
x2 - 6x - 16 = (x + 2)(x - 8)
x3 + 3x2 - 6x - 8 = (x - 2)(x2 + 5x + 4) = (x - 2)(x + 1)(x + 4)
(x + 4)(x + 2)
