Solving Rational Equations Tessshebaylo Multiplying both sides of an equation by variable factors may lead to extraneous solutions, which are solutions that do not solve the original equation. a complete list of steps for solving a rational equation is outlined in the following example. This topic covers: simplifying rational expressions multiplying, dividing, adding, & subtracting rational expressions rational equations graphing rational functions (including horizontal & vertical asymptotes) modeling with rational functions rational inequalities partial fraction expansion.
Solving Rational Equations Tessshebaylo Rational equations have a variable in the denominator in at least one of the terms. our goal is to perform algebraic operations so that the variables appear in the numerator. in fact, we will eliminate all denominators by multiplying both sides of the equation by the least common denominator (lcd). How to solve rational equations the first step to solving rational equations is determining the values that make the denominators zero. these values are not allowable solutions because they lead to an indeterminate form. In today’s lesson, you will learn and practice solving rational equations. as you will see, these are any equation involving a fraction, also known as a rational number in math talk!. Solving rational equations instructions this page includes exercises that you should attempt to solve yourself. you can check your answers and watch the videos explaining how to solve the exercises.

The rational equation we started with produced one answer, = −9. however that one answer is not valid because replacing with −9 results in two of the rational expressions having denominators of zero. We will use the same strategy to solve rational equations. we will multiply both sides of the equation by the lcd. then, we will have an equation that does not contain rational expressions and thus is much easier for us to solve. However, this may not always be the case. multiplying both sides of an equation by variable factors may lead to extraneous solutions, which are solutions that do not solve the original equation. a complete list of steps for solving a rational equation is outlined in the following example. Some literal equations, often referred to as formulas, are also rational equations. use the techniques of this section and clear the fractions before solving for the particular variable.
