x2 - 6x - 16 = (x + 2)(x - 8)
16 + 6x - x2 = 16 + 8x - 2x - x2 = 8*(2 + x) - x*(2 + x) = (8 - x)*(2 + x)
(x - 2)(x - 4)
x2-6x can be factored into x(x-6). Simply factor out the "x" from both factors.

x2 + 6x + 8 = (x + 4)(x + 2)
x2 - 6x - 16 = (x + 2)(x - 8)
x2 + 6x - 2 can not be factored
16 + 6x - x2 = 16 + 8x - 2x - x2 = 8*(2 + x) - x*(2 + x) = (8 - x)*(2 + x)
x2 + 6x + 8 =(x + 2)(x +4)
(x - 2)(x - 4)
x2-6x can be factored into x(x-6). Simply factor out the "x" from both factors.

If you mean: 8x2-56x-64 which becomes x2-7x-8 and is (x-8)(x+1) when factored
x2 + 2x - 48 = x2 + 8x - 6x - 48 = x(x + 8) - 6(x + 8) = (x - 6)(x + 8)
-x2 + 6x + 16 = -(x2 - 6x - 16) = -(x - 8)(x + 2) = -(8 - x)(x + 2)
x2-6x+8 = (x-2)(x-4) when factored
