Answer:
D
Step-by-step explanation:
Let's factor x2+8x+16
x2+8x+16
The middle number is 8 and the last number is 16.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 8
Multiply together to get 16
Can you think of the two numbers?
Try 4 and 4:
4+4 = 8
4*4 = 16
Fill in the blanks in
(x+_)(x+_)
with 4 and 4 to get...
(x+4)(x+4)
Answer:
(x+4)(x+4)
