Can someone pls give me an explanation on how to do this pls

Answer: This is a perfect square trinomial. You are trying to find the binomials that multiply to that. In order to do that, you do the following.
Multiply 2x^2 by 4 (A times C)
Find what numbers multiply to give you 8 and add to give you 7.
When you do this, you will notice that there are no numbers that do this. That makes your answer D. NONE OF THESE.
Step-by-step explanation:
Answer:
J
Step-by-step explanation:
F is impossible because -1 x 4 = -4
G is impossible because 1 x -4 = -4
Try to solve H
2x^2+8x+x+4 = 2x^2+9x +4 (is not correct)
