Answer:
C. (x + 4) and (x - 1)
Explanation:
The middle number is 3 and the last number is -4.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 3
Multiply together to get -4
Can you think of the two numbers?
Try -1 and 4:
-1+4 = 3
-1*4 = -4
Fill in the blanks in
(x+_)(x+_)
with -1 and 4 to get...
(x + 4) and (x - 1)
