What is the index? What is the radicand?

2. Radical Equations
Analysis

3. Aim: to solve radical equations
Radical Equation: an equation that has a variable in a radicand

4. Which of the following is a radical equation?

5. The following are radical equations:
The following are not radical equations:

6. In general, to solve a radical equation when just one term has a variable in the radicand, isolate that term on one side of the equation. Then, if the index is 2, square both sides of the equation
Always check your solutions!

8. Similar techniques can be applied to radical equations involving radicals with indexes greater than 2. Instead of squaring both sides, raise each side to a power equal to the index of the radical
