Radical equations are equations where the variable is inside a radical symbol. This document provides an example of solving a radical equation by taking the square root of both sides and then isolating the variable. It also lists some online resources for learning more about solving radical equations, including worksheets, lessons, and tutorials on taking various steps like taking square roots and isolating variables.
