- Solve a radical equation for a given variable
- Identify extraneous solutions and know what do with them
- Solve a radical inequality for a given variable

In the previous sections we have worked with radical expressions and have developed a better understanding of the properties of radicals. Now, we will continue working with radicals to solve equations and inequalities.

Tutorial

When solving a radical inequality, we approach the problem the same way as we would for a radical equation. What is the only difference?
