Videos and lessons to help High School students learn how to use
the method of completing the square to transform any quadratic
equation in *x* into an equation of the form (*x*?*p*)^{2}*
= q* that has the same solutions. Derive the quadratic
formula from this form.

- Transform a quadratic equation written in standard form to an
equation in vertex form (
*x*?*p*)^{2}*= q*by completing the square. - Derive the quadratic formula by completing the square on the standard form of a quadratic equation.
