    I can't factor that to get integer roots. Sorry. I'd try the Quadratic Formula.

    hi

    If it is not necessary to solve it with factorization:

    2x^2 + 3x -4:

    ax^2+bx+c=0

    ===>[DELTA]=b^2-4ac

    and x = (-b+,-[DELTA]) / 2a

    x1 = 0.85078

    x2 = -2.3508

    use the quadratic formula.
