Clearing denominators
WebMar 28, 2024 · For this reason, we will take care to ensure that the denominator is not 0 by making note of restrictions and checking our solutions. Solving rational equations involves clearing fractions by multiplying both sides of the equation by the least common denominator (LCD). Example 6.7.1: Solve: 1 x + 2 x2 = x + 9 2x2. Solution WebDec 5, 2024 · Just like clearing denominators, you are multiplying by 1 in various forms. 1000 g 1 k g = 1 so you can multiply by it any time you want. You choose the forms of 1 to get the units from what you have to what you want. The last two terms on the right in your equation are forms of 1.
