1
Solving Radical Equations

2
The simplest kind of radical equation is one like this

3
To solve it, you need only square both sides of the equation.

4
Of course, most radical equations are not that simple. Usually there are several terms on each side.

5
So the first step in solving a radical equation is to get it in a form similar to the first problem we looked at; that is, get the radical alone on one side of the equation. Then square both sides of the equation and solve the resulting equation.

6
Example Subtract 2 from each side. Divide both sides by 2. Square both sides Subtract 1

7
Lets practice a few. Solve:

8
Check your answers. Solve X=81 X=49 X=9

9
Apply your understanding Solve Find a number such that the square root of 3 less than twice the number is equal to 3. (write the equation and then solve it)

10
Check your answer. Write an equation Square both sides Add 3 to both sides Divide both sides by 2
