The vertex form of a quadratic equation is written like f (x) = a(x - h)2 k, with the letter h and the letter k being the vertex point of the parabola. It can be used to create an equation when the vertex of the parabo... More » Math Geometry

A vertex form converter is a computer program or a web application that converts between the standard form of a quadratic equation and its vertex form. Because vertex form is easier to visualize and plot than standard fo... More » Math Math Calculators

Change a quadratic function to its vertex form by applying a process called completing the square, then isolate the y variable on one side of the equation. The vertex form is represented by the formula y = a(x-h)^2 k, ... More » Math Algebra
