Question 10 • Math 7 B (M12 25/26 S2)

What is the factored form of x2 – x – 2?

Answer
A
(x – 2)(x + 1)
B
(x + 2)(x + 1)
C
(x – 2)(x – 1)
D
(x + 2)(x – 1)

Explanation

To factor x² − x − 2, find two numbers whose product is −2 and whose sum is −1. Those numbers are −2 and 1, so the expression factors as (x − 2)(x + 1), which is choice A.
