Question

How do you solve a radical equation? What are the steps in doing so?

Answer 1

Radical Equation:

1. Isolate the radical expression.

2. Square both sides of the equation: If x = y then x2 = y2.

3. Once the radical is removed, solve for the unknown.

4. Check all answers.

Another way of saying it:

1. Isolate the radical expression involving the variable. ...

2. Raise both sides of the equation to the index of the radical.

3. If there is still a radical equation, repeat steps 1 and 2; otherwise, solve the resulting equation and check the answer in the original equation.
