How do you solve this problem?

x = - 1, x = 3

Step-by-step explanation:

Consider the factors of the constant term ( - 3) which sum to give the coefficient of the x- term (- 2)

The factors are - 3 and + 1

(x - 3)(x + 1) ← in factored form

To solve equate to zero, that is

(x - 3)(x + 1) = 0

Equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3

x + 1 = 0 ⇒ x = - 1
