Provide an appropriate response.Explain in your own words why possible solutions of radical equations must be checked.
What will be an ideal response?
The square of a number is equal to the square of its opposite. Thus, while squaring both sides of a radical equation allows us to find the solutions of the original equation, this procedure can also introduce numbers that are not solutions of the original equation.
