    Finding; x

    Gosh, this is so embarrassing! >_<

    I have done these dozens of times! But I'm having a bad day, and can't seem to wrap my brain around it.
    It's the whole squared x that is frustrating me.


    So...

    Solve for x;

    x^2 - 15x + 36 = 0


    Gah! I really don't know why my brain isn't comprehending this.
