Chapter 5 Sec 8 Radical Equations

2 of 7 Chapter 5 Sec 8: Radical Equations Solve Radical Equations Equations with radical that have variables in the radicand are called radical equations. To solve radical equations, complete the following steps: Step 1: Isolate the radical, if there are more than one radicals in the equation pick one and isolate. (get the radical by itself on one side of the equation) Step 2: Raise each side of the equation to a power equal to the index of the radical. Step 3: Test your answer for extraneous solutions.
