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 . WebWhen you add or subtract fractions, you begin by finding a common denominator. This is what you must do when you add or subtract rational expressions. We seek the least common denominator, LCD, because this produces the easiest calculations. You can add or subtract rational expressions only when you have a common denominator.
