Question

Wich is a factor of x^2+ 5x-24?

Answer 1

Answer:

(x−3)(x+8)

Step-by-step explanation:

Let's factor x2+5x−24

x2+5x−24

The middle number is 5 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 5

Multiply together to get -24

Can you think of the two numbers?

Try -3 and 8:

-3+8 = 5

-3*8 = -24

Fill in the blanks in

(x+_)(x+_)

with -3 and 8 to get...

(x-3)(x+8)

Answer:

(x−3)(x+8)

Hope this helps.
