Answer:

( x + 3 )(x - 6)

Explanation:

if you factor x2−3x−18

x2−3x−18

The middle number is -3 and the last number is -18.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get -3

Multiply together to get -18

Can you think of the two numbers?

Try 3 and -6:

3+-6 = -3

3*-6 = -18

Fill in the blanks in

(x+_)(x+_)

with 3 and -6 to get...

(x+3)(x-6)
