Rational Function Simplifier

Simplify complex rational expressions with ease. Just input the numerator and denominator polynomials to get a simplified, readable result.

Enter the polynomial for the numerator. Use 'x' as the variable.

Enter the polynomial for the denominator. Use 'x' as the variable.

Simplified Rational Function

How it Works

Rational function simplification involves reducing the expression to its simplest form by canceling out common factors in the numerator and denominator polynomials. This tool uses symbolic mathematics to identify and eliminate these common factors, providing you with the most concise representation of the rational function.

Understanding Rational Function Simplification

A rational function is essentially a fraction where both the numerator and the denominator are polynomials. Simplifying these functions means reducing them to their lowest terms, much like simplifying regular fractions.

Key Concepts:

Example:

Consider the rational function \( \frac{x^2 - 1}{x + 1} \). To simplify it, we factor the numerator: \( x^2 - 1 = (x - 1)(x + 1) \). Then, we can cancel the common factor \( (x + 1) \) from the numerator and the denominator, resulting in the simplified form \( x - 1 \).

Use Cases:

This tool uses math.js for symbolic calculations and MathJax for rendering mathematical expressions.
