Quadratic Vertex is a powerful learning aid that combines interactive Coaching Calculators and Guides to help students master finding the vertex of the graph of a quadratic function by completing the square.

Work with the Coaching Calculator step by step,

- Writing in general form
- Factoring out coefficient of x² if necessary
- Completing the square
- Writing in vertex form
- Stating the coordinates of the vertex

or go straight to a particular step.

The Guide features worked examples where the coefficient of x² is one and not equal to one.

Applications include sketching the graphs of quadratic functions.

It's ideal for students as the menu design reinforces each problem solving step and examples highlight and simplify algebra that students find hard.
