Equations | Algebra 2 | Math | Khan Academy
Let's tackle a greater variety of equations, like rational and radical equations. 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 estimate a solution for any kind of equation!
