    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?

    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.
