    A=2 B=9 and C=-18 So we need to find 2 numbers that when you multiply it equals A*C=2*18=36 and when you add these 2 numbers you get B=9

    Yup. Pick an answer choice. Multiply it out and see if you get \(2a^2 +9a -18\)

    @brianasosaa You will find many people in this world that you may think of as mean. If you want them to help you, you might have to overlook it.

    It would of been correct if the expression had of been: 2a^2 - 9a -18 but alas that was not the case.
