Answer:

J

Explanation:

F is impossible because -1 x 4 = -4

G is impossible because 1 x -4 = -4

Try to solve H

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.
