Question

Which are factors of x2 – 4x – 5? Select two options.

(x – 5)
(x – 4)
(x – 2)
(x + 1)
(x + 5)

Answer 1

(x - 5) and (x + 1)

Step-by-step explanation:

Use the X method and plug in the numbers from the X to the new equation.

x2 + (x − 5x) − 5

Now group the factors

x(x + 1) − 5(x + 1)

Rewrite in factored form

(x − 5) (x + 1)

Maybe that made some sense, I hope it did

Answer 2

(x-5) and (x+1)
