Question

What is the factored form of x2 – 6x – 16? (x – 4)(x – 2) (x + 4)(x – 2) (x – 2)(x + 8) (x – 8)(x + 2)

Answer 1

`\left(x+2\right)\left(x-8\right)`

Explanation:

`x^2-6x-16`

`x^2-8x+2x-16`

`x(x)+x(-8)+2(x)+2(-8)`

`\left(x+2\right)\left(x-8\right)`

Answer 2

(x-8) (x+2)

Explanation:

x^2 – 6x – 16

Factor

What 2 numbers multiply to -16 and add to -6

-8 *2 = -18

-8+2 = -6

(x-8) (x+2)
