Chapter 11 - Rational Expressions and Functions - 11-4 Adding and Subtracting Rational Expressions - Lesson Check: 6

Answer

Finding the LCD of two rational expressions and the LCD of two numerical fractions are very similar. For both rational expressions and numerical fractions, you must list out your factors of each denominator, and use them to find the Least Common Multiple. However, with rational expressions, you will have variables that may require more difficult factoring.
