    We don't give full solutions here. When you show that you have made an attempt and show exactly where you are stuck, then we can help you further.

    Re: plz help and include answer plz

    Here's some things to get you started:

    1) This problem can be re-written as a^2 + a = 12 by substituting some bits for a (I'll let you figure that out).
    2) Second order equations (of which this is one) have at most 2 solutions.
    3) solve the equation in part (1)
    4) express a in terms of x
    5) the larger of the two solutions for x is your answer

    note: it is possible for second order equations (quadratics) to have only a single solution.
