Don't forget to check your solution and make sure that your answer is not an excluded value. When multiplying two rational expressions there is always a risk of getting false solutions or extraneous solutions. Video lesson Solve the rational equation ...
An important step in solving rational equations is to reject any extraneous solutions from the final answer. Extraneous solutions are solutions that do not satisfy the original form of the equation because they produce untrue statements or are excluded values that cause a denominator to equal 00....

While adding and subtracting rational expressions can be a royal pain, solving rational equations is generally simpler, even if rational expressions are added within those equations. (Note that I'm not saying that solving rational equations is "simple"; I'm only saying that it's simpler.) This...
Rational functions are those functions that are the division of two polynomials. To solve an equation involving rational functions, we cross multiply the numerators and denominators. Then we move all our terms to one side. Then we use our algebra skills to solve. Read Solving Equations & ...
