    a quadratic equation is of the form \[ax ^{2}+bx+c\]

    It wouldn't hurt to know what a linear equation is too! y=mx+b

    yes, that is the standard form of expressing a quadratic equation. \[ax ^{2}+bx+c =0\]

    I didn't put the =0 in my earlier equation. It wouldnt be an equation it it doesnt equate to something :D

    No, it is not D. A quadratic equation is a polynomial raised to the second degree.

    In mathematics, a quadratic equation is a polynomial equation of the second degree. The general form is ax^2+bx+c=0, where x represents a variable, and a, b, and c, constants, with a ≠ 0. (If a = 0, the equation becomes a linear equation.)

    and, btw, ALL equations can be graphed. graph, are, well, graphical representations of equations.

    so now, it is easy to see which choice is not a quadratic equation, right?

    you are welcome. In math you just have to break down your problems into smaller parts and try to understand what the smaller parts mean. If you don't understand the smaller part, break it into smaller parts still. Apply logic and you will get your answer. :)
