Answer:
(x+11)(x−11)
Step-by-step explanation:
The middle number is 0 and the last number is -121.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 0
Multiply together to get -121
Can you think of the two numbers?
Try 11 and -11:
11+-11 = 0
11*-11 = -121
Fill in the blanks in
(x+_)(x+_)
with 11 and -11 to get...
(x+11)(x-11)
