    this cannot be factored. use the quadratic formula.

    what is the quadratic formula?

    The solutions to the equation ax^2 + bx + c = 0 are given by the formula:

    x = \frac {-b \pm \sqrt{b^2 - 4ac}}{2a}

    this is called the quadratic formula. of course, here you have y instead of x, but that doesn't matter

    a = 3 b = 6 c = 2

    so

    x= -6(+-)Square root of(6)^2-4(3)(2) all divided by 2(3)

    By the way if your trying to do the discriminant it is

    b^2-4ac > 0, 2 solutions
    b^2-4ac = 0 ,1 solution
    b^2-4ac < 0 , no solution
