**Solving Rational Equations by Using the LCD Math Forum**

The equations that we will be working with in this section all have rational expressions (fractions - yuck!). After a few magical steps, we can transform these equations with rational expressions into linear equations.... these, you must find the LCD of all the rational expressions in the equation. 11 Example 2A Solving Rational Equations by Using the LCD. Solve each equation. Check your answer. Step 1 Find the LCD. 2x(x 1) Include every factor of the denominator. Step 2 Multiply both sides by the LCD. Distribute on the left side. 12 Example 2A Continued. Step 3 Simplify and solve. Divide out common factors

First if the rational equation is a proportion (one fraction = one fraction) than cross multiply to solve 2. However if the rational equation is not a proportion find the LCD of all the rational terms; multiply the entire equation by the LCD to clear fractions and solve remaining equation...Solve the equation: x squared minus x squared minus 4 over x minus 2 is equal to 4. And they tell us that x won't or cannot be 2 because if it was 2, then this would be undefined.

## How To Find The Lcd In Rational Equations

### By Mary Jane Sterling . Any equation with one or more rational terms (or fractions) is a rational equation. Although these equations arenâ€™t always easy to handle, you can turn them into quadratic equations by finding their least common denominator, or LCD.

- Proportions are nice to work with when youâ€™re solving rational equations, because you can eliminate the fractions or change them so that they feature better denominators. A proportion is an equation in which one fraction is set equal to another. For example, the equation is a proportion. When you have the proportion the following are [â€¦]
- Solve the equation, 5 over 2x minus 4 over 3x is equal to 7 over 18. And they tell us that x can't to be equal to 0, because that would make these two expressions here undefined. Hopefully the answer here is not 0, and then this becomes-- this is kind of extra, unnecessary information. So let's
- About This Quiz & Worksheet. This quiz and attached worksheet will help gauge your understanding of rational equations and the least common denominator.
- A rational expression is a fraction where at least one term is a polynomial of the form axÂ² + bx + c, where a, b and c are constant coefficients.
