A power learning aid combining Guides, Practice and Coaching Calculators to help students master factoring of quadratic trinomials.

The Box or Grid Method factors harder trinomials such as 3x² + 7x + 4, but also handles simple cases.

Its similar to factoring by Grouping or the AC method, but many students find it easier because of the routine process involved combined with the visual nature of the box.

Students develop their skills quickly as they work with the calculator and see each step of a process in detail.

- Drawing the box
- Finding the product and sum
- Completing the box
- Factoring rows and columns
- Reading off the factors

Students learn quickly when they focus on a particular step and investigate what happens when the sign of the x-coefficient switches between positive and negative.

For convenience, the app also has Coaching Calculators covering many quadratic factoring methods :

- factoring by Guess and Check or Trial and Error method
- factoring by Grouping or AC method
- factoring by Difference of Squares

The in depth Guides show each problem solving step and highlight and simplify algebra that students find hard.
