Answer:
(d+4)(d−4)
Step-by-step explanation:
Let's factor d2−16
d2−16
The middle number is 0 and the last number is -16.
Factoring means we want something like
(d+_)(d+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 0
Multiply together to get -16
Can you think of the two numbers?
Try 4 and -4:
4+-4 = 0
4*-4 = -16
Fill in the blanks in
(d+_)(d+_)
with 4 and -4 to get...
(d+4)(d-4)
Answer:
(d+4)(d−4)
