    The factors of the constant at the end of your equation are the possible solutions to this problem. What are the different factors of 6?

    1, 2, 3, and 6

    Right. Both positive and negative, so you have 8 possible solutions.

    ok, so is the group x = 3, x = 1, and x = -2 a possibility?

    Since this is a third degree polynomial, there can only be three. And since you know one is 2, use synthetic division to find the others. Yes, the group you listed is certainly a possibility.
