Description
Quadratic Inequalities is a combined Guide and Coaching Calculator that helps students solve quadratic inequalities by sketching their associated graphs.
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.
This learning aid includes a Coaching Calculator for finding x-intercepts . It solves associated quadratic trinomial equations by factoring or completing the square.
The calculator handles integer coefficients up to 149.
Students develop their skills quickly as they work with the calculator and see each step of a process in detail.
