7.3: Adding and Subtracting Rational ExpressionsLearn how to add and subtract rational expressions with common and unlike denominators, and rational functions. See examples, exercises, and explanations with polynomials and factored forms.
To add or subtract rational expressions with a common denominator, add or subtract the numerators and place the result over the common denominator. We always simplify rational expressions. Be sure to factor, if possible, after you subtract the numerators so you can identify any common factors.

Study Guide - Adding and Subtracting Rational Expressions - SymbolabAdding and Subtracting Rational Expressions. Adding and subtracting rational expressions works just like adding and subtracting numerical fractions. To add fractions, we need to find a common denominator. Let’s look at an example of fraction addition.

Study Guide - Adding and Subtracting Rational Expressions - SymbolabHow To: Given two rational expressions, add or subtract them. Factor the numerator and denominator. Find the LCD of the expressions. Multiply the expressions by a form of 1 that changes the denominators to the LCD. Add or subtract the numerators. Simplify. Example: Adding Rational Expressions. Add the rational expressions:
