    derivation of the Quadratic Formula

    Hey, for homework i am soposed to solve the equation ax^2 + bx + c = 0. I know that the answer is the quadratic formula, but I am not sure why. If you could explain the steps to get to the quadratic formula for this equation that would be great

    A quadratic equation is a second degree polynomial equation, which has the form: ax^2+bx+c =0

    The quadratic formula is:

    \displayfrac{ x = \dfrac{-b \pm \sqrt{b^2-4ac}}{2a}}

    I understand what the quadratic formula is. How do I get from the first equation to the quadratic formula, like how would I solve for ax^2 + bx + c = 0?
