Answer:
Let's factor n2+15n−324
n2+15n−324
The middle number is 15 and the last number is -324.
Factoring means we want something like
(n+_)(n+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 15
Multiply together to get -324
Can you think of the two numbers?
Try -12 and 27:
-12+27 = 15
-12*27 = -324
Fill in the blanks in
with -12 and 27 to get...
(n-12)(n+27)
(n−12)(n+27)
