Solving an equation with a square root

What is the first step in solving a radical equation?

• Divide both sides by a constant

• Add a constant to both sides

• Isolate the variable

• Multiply both sides by a constant

Why do we square both sides of the equation when solving a radical equation?

• To eliminate the square root

• To make the equation linear

• To simplify the equation

• To isolate the constant

What should be done after isolating the variable in a radical equation?

• Divide both sides by a constant

• Check for extraneous solutions

• Multiply both sides by a constant

• Add a constant to both sides

What is an extraneous solution?

• A solution that does not satisfy the equation

• A solution that satisfies the equation

• A solution that is a fraction

• A solution that is negative

How do you verify if the solution to a radical equation is correct?

• By checking if it is less than 10

• By checking if it satisfies the original equation

• By checking if it is a whole number

• By checking if it is positive
