ARationalExp Rational Expressions is a quick reference guide to the simplification, addition and subtraction and multiplication and division of rational expressions.

Rational expressions are also known as algebraic fractions.

The app 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).

The app covers the multiplication and division of rational expressions such as

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

The app covers the simplification of rational expressions such as

(x² + 6x + 8)/(x + 2)
(x² – 5x + 6)/(14 + 3x – 5x²)
(3x² – 9x)/(x^4 – 81).

Reduction questions cover:

– Factoring out GCFs
– Factoring linear numerators/denominators
– Factoring quadratic numerators/denominators
– Dividing out or canceling common factors

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

Examples highlight and simplify algebra that students find hard.
