What is the factored form of x2 − 4x − 5? (x + 5)(x − 1) (x + 5)(x + 1) (x − 5)(x − 1) (x − 5)(x + 1)

(x - 5)(x + 1)

Step-by-step explanation:

Given

x² - 4x - 5

Consider the factors of the constant term (- 5) which sum to give the coefficient of the x- term (- 4)

The factors are - 5 and + 1, since

- 5 × 1 = - 5 and - 5 + 1 = - 4, hence

x² - 4x - 5 = (x - 5)(x + 1) ← in factored form

(x - 5)(x + 1)
