Answer:
(x+9)(x+9)
Step-by-step explanation:
Let's factor x^2+18x+81
x^2+18x+81
The middle number is 18 and the last number is 81.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 18
Multiply together to get 81
Can you think of the two numbers?
Try 9 and 9:
9+9 = 18
9*9 = 81
Fill in the blanks in
(x+_)(x+_)
with 9 and 9 to get...
(x+9)(x+9)
