A power learning aid combining Guides, Practice and Coaching Calculators to help students master rational expression or rational fraction simplification.
Practice and Coaching Calculators take you step-by-step through simplification of expressions such as :
(6x³ + 7x² - 1)/(2x² + 3x + 1)
(x² + 6x + 8)/(x + 2)
(x² - 5x + 6)/(14 + 3x - 5x²)
(3x - 9)/(6x - 12).
Detailed steps :
- Factoring out numeric or algebraic factors
- Factoring linear numerators/denominators
- Factoring quadratic numerators/denominators
- Factoring cubic 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.
