Description

ARationalExp Rational Expressions is a powerful learning aid that combines Coaching Calculators and Guides to help students master the simplification of rational expressions or algebraic fractions.

The Coaching Calculator covers the simplification of rational expressions such as

(x² + 6x + 8)/(x + 2)

(x² - 5x + 6)/(14 + 3x - 5x²)

(3x - 9)/(6x - 12).

Detailed steps :

- Factoring out GCFs

- Factoring linear numerators/denominators

- Factoring quadratic numerators/denominators

- Dividing out or canceling common factors

The Guide also covers the addition and subtraction of rational expressions such as

3(x - 2)/2 - (x + 1)/5

12/(x - 1) + 5/x

3/(x + 1) + 2x/(x² - 6x - 7)

and the multiplication and division of rational expressions such as

(x² - 1)/(9x² - 1) * (6x + 2)/(3x² - 3x).

It's ideal for students as the menu design reinforces each problem solving step.

Examples highlight and simplify algebra that students find hard.

The app also includes a Guide to solving rational equations and Coaching Calculators and Guides for factoring quadratic trinomial expressions.

What's New in Version 7.0

iOS 10 compatibility and bug fixes.
