Quadratic general to standard form

Wednesday, August 6th, 2008

When solving quadratic equations and sketching parabolas you can get the required points onto your graph very quickly if you know how to convert from the general form of y=ax^{2}+bx+c to the standard form of y=a\left(x-h\right)^{2}+k. (See Standard Quadratic Form for the reasons why.) This article explains how to complete the square to acheive this.

Standard Quadratic Form

Friday, August 1st, 2008

This is the “standard” form of the quadratic equation:

y=a(x-h)^{2}+k where a\neq0

This article will describe how to find the vertex, x-intercepts and y-intercepts for this form of a quadratic equation.
