I am having a problem figuring out trinomials when there is a number added to the first term. I understand the second sign determines both signs below and the sign on the left determines what they will be. I also believe I figured out the first term. The problem is there are five different options with this problem. Is there a fast way to determine if you are on the right track without having to FOIL all five options?

4x^2 + 6x + 9

(x + 1) (4x + 9)

(x + 9) (4x + 1)

(x + 3) (4x + 3)

(2x + 1) (2x + 9)

(2x + 3) (2x + 3)
