ARationalExp Rational Expressions 3.0
ARationalExp Rational Expressions - ARationalExp Rational Expressions is a powerful learning aid that combines an interactive Coaching Calculator and Guide 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.
