Question

Factor completly: x^2-2x-24

Answer 1

(x+4)(x−6)

Explanation:

Factoring x2−2x−24

x2−2x−24

The middle number is -2 and the last number is -24.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get -2

Multiply together to get -24

Can you think of the two numbers?

Try 4 and -6:

4+-6 = -2

4*-6 = -24

Fill in the blanks in

(x+_)(x+_)

with 4 and -6 to get...

(x+4)(x-6)

Answer 2

x^2-2x-24 = (x - 6)(x + 4)

cause
(x - 6)(x + 4)
= x^2 - 6x + 4x - 24
= x^2 - 2x - 24

answer
(x - 6)(x + 4)

hope it helps
