I assume you mean....,
X2 + 2X - 8
what two factors of - 8 add up to 2 ?
(X- 2)(X +4)
=========
X = 2
X = - 4
8
3x2-2x-8 = (3x+4)(x-2) when factored
2(x^2 - 8)
2x2-1x-120 = (2x+15)(x-8) when factored
If you mean: (2x-7y)(x+y) then it is 2x squared -5xy -7y squared
8
(x+2)(x−4)
3x2-2x-8 = (3x+4)(x-2) when factored
8
(x + 2)(x - 4)
5x lolzz 8)
2x to the fourth
3x squared - x squared = 2x squared
2(x^2 - 8)
No. x squared is x times x, whereas 2x is x + x.
2x2-1x-120 = (2x+15)(x-8) when factored
If you mean: (2x-7y)(x+y) then it is 2x squared -5xy -7y squared
