Rational Expressions Calculator
Two tools in one: simplify a rational expression by factoring and canceling (with excluded values), or combine two rational expressions with ×, ÷, +, −. Every answer comes with the working shown step by step.
Simplify a rational expression
Type the numerator and denominator as polynomials with ^ for powers. The tool factors both, cancels, and lists excluded values.
Combine two rational expressions
Enter each expression as a numerator and denominator, pick the operation, and get the simplified result with its domain.
