This video shows a method for finding the least common denominator of rational expressions. I've posted at least 2 other videos with methods, explanations, and examples for finding the LCD.
 What is the least common denominator or LCD?
 How do you find the least common denominator of algebraic fractions?
 What is the least common denominator of 3/2x^2 and 5/6xy?
 How do you find the LCD of algebraic fractions if the denominators are not factored?
 How do you find the LCD of x/(9x + 9) and (x + 4)/6x?
 What is the LCD of (3x + 5)/(x  7) and 4/(x + 5)?
 What is the least common denominator of 5/(7x  14) and 3x/(x^2  4)?
 How do you find the least common denominator of 3 algebraic fractions?
 What is the LCD of 4/(3x + 15), 1/(4x  20), and 1/(x^3  25x)?
This lesson shows how to find least common denominators when there are variables involved. The methods shown for finding the least common denominator are the same as with just numbers; you will just have to deal with algebraic expressions now. Several examples are shown and explained in this video.
