Extraneous and missing solutions - Wikipedia, the free encyclopedia
In mathematics, an extraneous solution represents a solution, such as that to an equation, that emerges from the process of solving the problem but is not a valid solution to the original problem. A...

We call x=-2 an extraneous solution. To avoid incorrectly reporting extraneous solutions to equations you should check whether or not each value that arises from the solution method is a solution by substituting that value into the original equation.

What is an extraneous solution and in what cases do you get one? ... They are extraneous because they are not solutions of the original problem. This answers your second question. To tell if a "solution" is extraneous you need to go back to the original problem and check to see if it is actually a solution.

Where you might see an extraneous solution is situations where you have to square both sides to reach a solution or where you have a fraction with an algebraic expression in the denominator. There is an example of each case in the answer to a previous question.

An extraneous solution ... Notice we see the solution that is at x = 3.58113883 but we don't see the other solution.  The reason is that x = .418861169 is a solution of the quadratic equation we found in order to solve the logarithmic equation.  Sometimes, such transformations of equations give us solutions that are...

While adding and subtracting rational expressions is a royal pain, solving rational equations is much simpler. ... (Note that I don't say that it's "simple", ... This equation is so simple that I can solve it just by looking at it: since I have two-thirds equal to x-thirds, clearly x = 2. The reason this was so easy to solve is...
