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.
