Quadratic Equations

A power learning aid combining Practice, Coaching Calculators and Guides to help students master the solving of quadratic equations.

Coaching Calculators solve quadratic equations by :

- completing the square
- quadratic formula
- factoring

Students learn quickly by working with the calculator and seeing each step of the process in detail.

Completing the square for example:

- Dividing by coefficient of x²
- Taking constant term to right hand side
- Completing the square
- Taking the square root of both sides
- Simplifying and solving

Practice includes examples from basic such as x² + 3x + 2 = 0 to equations with rational (fractional) coefficients.

Guides have a comprehensive set of examples
