    Put it in the form ax^2 + bx + c = 0



    If you cannot factor it easily into two momialsw, then use this "quadratic equation" for the two solutions.

    x = [-b +/- sqrt(b^2-4ac)]/2a

    +/- means "plus or minus"
    "sqrt" means "square root of"

    They should me teaching you thisw equation as part of your algebra course.
