How to subtract rational functions
WebWrite each expression using the LCD. Make sure each term has the LCD as its denominator. Add or subtract the numerators. Simplify as needed. Example 1: Add 1 3 a + 1 4 b . Since the denominators are not the same, find the LCD. Since 3 a and 4 b have no common factors, the LCM is simply their product: 3 a ⋅ 4 b . WebMethod 2: Multiplying through by the common denominator: The lowest common denominator is 15. Rather than converting the fractions to this denominator (something that would be required if I were adding or subtracting these rational fractions), I can instead multiply through (that is, multiply both sides of the equation) by 15.
