In this video, we explain how and why we get extraneous solutions, by understanding the logic behind the process of solving equations. video https://cdn.kastatic.org/ka_thumbnails_cache/8d3c200c-9f06-49f2-b6aa-3d50758d477f_1280_720_base.png Extraneous solutions Extraneous solutions are values that we get when solving equations that aren't really solutions to the equation.
