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.
It's similar to factoring by grouping or factoring by 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 target of the × and of the +
- Finding the signs of the integer pair
- 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.
Minor bug fixes and enhancements.

Confusing layout. Makes it difficult to get any use out of it.
BAD badbad !!!!
I got this app thinking it would actually help me these are just crappy crappy notes do NOT buy!
Not What I Was Looking For
Yes, it does what it should, it teaches you how to use a box to factor. What I need, and what I think you should make is an app that factors thing for you (by the way, I am not just a lazy algebra student) I would pay about five dollars Dow an app that did this well, this app however should be free
With Family Sharing set up, up to six family members can use this app.
