WebTo add/subtract rational expressions, first rewrite the fractions with a common denominator. If the denominators of two rational expressions are already the same, then we can add/subtract their numerators directly. In general, to add/subtract two rational expressions: Find the LCD (LCM) of their denominators.
WebOct 6, 2024 · Recall the steps to find the LCD (Chapter 2): Step 1 Factor (the denominators): 6 factors into 2 ⋅ 3 and 3 factors into 3 ⋅ 1. Step 2. List (the primes) 2,3. Step 3. (Form the) LCD: 2 ⋅ 3 = 6. Now that we have found the LCD, we use it to rewrite each rational expression to transform our problem from. 5 x 6 − 2 x 3.
