Answer:

(x−3)(x+9)

Explanation:

The middle number is 6 and the last number is -27.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get 6

Multiply together to get -27

Can you think of the two numbers?

Try -3 and 9:

-3+9 = 6

-3*9 = -27

Fill in the blanks in

(x+_)(x+_)

with -3 and 9 to get...

(x-3)(x+9)
