Shows a method for finding the Least Common Denominator of Algebraic Fractions.
- How do you find the least common denominator of algebraic fractions or rational expressions?
- What is an LCD and how do you find one in Algebra?
- How do you find the LCD of 3 different Algebraic fractions?
- What is the LCD of 5/9x^4y, 7/15xy^3, and 8/10x^2y^4?
- How do you deal with exponents when finding least common denominators?
- How do you find the LCD of 2x/(5x + 10), 9/75x^2, and 8/(x^2 - 4)?
- What is the LCD of (3x + 1)/(x^2 + 6x + 9), 8x/(5x^5 + 15x^4), and 9/10x?
- How do you find the least common denominator of 5x/(3x + 24), 9/(x^2 - 64), and (2x - 3)/(9x + 72)?
This lesson goes through a bunch more practice problems for finding the least common denominator of algebraic fractions. This time, 3 different fractions are used. The building up method of finding the LCD is explained, and all steps are shown very clearly in this video.
