    Depending on the calculator, there is a poly button or a solve button.

    If your calculator does not have those, use the "quadratic formula":
    The solutions to ax^2+ bx+ c= 0 are given by
    x= \frac{-b\pm\sqrt{b^2- 4ac}}{2a}.

    I had no idea that I could plug that weird-looking equation into the quadratic formula. How about that?
