Quadratic Inequalities

       iOS iPhone

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

The app includes Coaching Calculators for finding x-intercepts . The calculators solve the associated quadratic trinomial equations by factoring or completing the square.

The calculators handle integer coefficients up to 149.

The Guide takes you step through example questions :

- 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.
