What is the factored form of x^2 - x - 2

(x-2) (x+1)

(x+2) (x+1)

(x-2) (x-1)

(x+2) (x-1)

(x+1) (x-2)

Step-by-step explanation:

x^2-x-2

- 2

^

1 - 2

(x+1) (x-2)

(x - 2) (x + 1)

Step-by-step explanation:

Given

x² - x - 2

Consider the factors of the constant term ( - 2) which sum to give the coefficient of the x - term ( - 1)

The factors are - 2 and + 1, since

- 2 * 1 = - 2 and - 2 + 1 = - 1, thus

x² - x - 2 = (x - 2) (x + 1)
