Both radical and rational equations can have extraneous solutions, algebraic solutions that emerge as we solve the equations that do not satisfy the original equations.

Extraneous solutions are values that we get when solving equations that aren't really solutions to the equation. In this video, we explain how and why we get extraneous solutions, by …

Introduction In this article we will practice some problems that involve thinking about the conditions for obtaining extraneous solutions while solving radical equations.

Sal explains what square-root equations are, and shows an example of solving such an equation and checking for extraneous solutions. Created by Sal Khan and CK-12 Foundation.

Extraneous solutions of radical equations Learn Square-root equations intro Equation that has a specific extraneous solution

We'll see that sometimes, we get solutions that aren't really solutions at all, called extraneous solutions. We'll also solve more advanced systems, and learn how we can use graphs to …

Extraneous solutions are values that we get when solving equations that aren't really solutions to the equation. In this video, we explain how and why we get extraneous solutions, by …

Is there any possible situation in which a solution could satisfy both the original equation and the alternative 'hidden' equation that spawns our extraneous solutions?
