    (A+3) x (-2A2+15A+6) = (-2A3+XA2+51A+18)

    (3+3) x (-2*3*2+15*3+6) = (-2*3*3+X * 3*2+51*3+18)

    (6) x (-2*3*2=-12 + 15*3=45 + 6 = 51

    (6) x (-12 + 51=39)

    6 x 39 = (-2*3*3 = - 18) + x * 3*2 + (51*3+18=171)

    6 x 39 - 18 + x*3*2 + 171

    6 x 39 = 234

    234 - 171=63

    -18 + 5x=63

    X = 13.5
