Question

What is the factored form of x2 – X– 2? (x - 2)(x + 1) (x + 2)(x + 1)

(x - 2)(x - 1)
(x + 2)(x - 1)

Answer 1

(x+2)(x-1)

Explanation:

One way to factor is to FOIL your answer choices:

First: x(x)

Outer: x(-1)

Inside: 2(x)

Last: 2(-1)

Combine these values together and you get

x^2-x-2
