Quadratic Inequalities is a powerful learning aid to help students master the solving of quadratic inequalities by sketching their associated graphs.

Interactive Coaching Calculators and Guides combine to speed the learning process.

Coaching Calculators cover :

Solving quadratic inequalities

- by sketching associated graph

The Guide covers :

- Writing in general form
- Finding the graph shape
- Finding the x-intercept(s) if any
- Sketching the graph
- Finding the solution by inspection

Examples cover major types of quadratic inequalities and feature the finding of x-intercepts by factoring, completing the square and the quadratic formula.

The app also includes Guides and Coaching Calculators for solving quadratic equations :

- by factorization
- by quadratic formula
- by completing the square

for finding the x-intercepts of the associated quadratic graph.

The app also includes Guides and Coaching Calculators for finding the vertex of a quadratic graph :

- by completing the square
