Question

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

Answer 1

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.

Answer 2

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)
