Complex Fractions Find the LCD 2 - Visualizing Algebra

  • 0:00 - 0:06
    The LCD would be x squared times x plus 2. Remember we want the highest power of
  • 0:06 - 0:10
    any factor that appears in a denominator. So we know x is already a factor of x
  • 0:10 - 0:17
    squared, so we should use x squared. And X plus two for our LCD. Another way to
  • 0:17 - 0:22
    think about this, is to use our factor tree method to find the LCD of X squared
  • 0:22 - 0:27
    and X plus two. We use X squared here, since we know X is already a factor of X
  • 0:27 - 0:32
    squared. Now don't make the mistake of putting X as the common factor here. X
  • 0:32 - 0:38
    plus two is one factor. Wgereas X squared has the factors of X and X. The only
  • 0:38 - 0:44
    common factor for X squared and the quantity X plus two is one. This also makes
  • 0:44 - 0:50
    sense because this X is a term inside this factor. So our LCD is X squared times
  • 0:50 - 0:54
    one times the quantity X plus two.
