You have seen that there is more than one way to solve rational equations. Because both of these techniques manipulate and rewrite terms, sometimes they can produce solutions that do not work in the original form of the equation. These types of answers are called extraneous solutions. That is...
(Note that I'm not saying that solving rational equations is "simple"; I'm only saying that it's simpler.) This is because, as soon as you go from a rational expression (that is, something with no "equals" sign in it) to a rational equation (that is, something with an "equals"...

In this section, we look at rational equations that, after some manipulation, result in a linear equation. If an equation contains at least one rational expression, it is a considered a rational equation. Recall that a rational number is the ratio of two numbers, such as 2323 or 7272. A...
