How to Solve a Radical Equation by Squaring Both Sides

The video tutorial explains how to solve an equation by squaring both sides and applying the FOIL method to multiply binomials. It demonstrates the process of isolating variables and solving for x, followed by verifying the solution through substitution.

What is the first step to undo a square root in an equation?

• Subtract the same number from both sides

• Divide both sides by the same number

• Add the same number to both sides

• Square both sides of the equation

When using the FOIL method, what does the 'O' stand for?

• Opposite

• Over

• Order

• Outer

After applying the FOIL method, what should you do next to simplify the equation?

• Divide the terms on both sides

• Add the terms on both sides

• Subtract the squared terms on both sides

• Multiply the terms on both sides

What is the first operation to perform when isolating a variable?

• Undo addition or subtraction

• Undo division

• Undo exponentiation

• Undo multiplication

How do you verify the solution of an equation?

• By using a calculator

• By comparing with a different equation

• By checking if the solution satisfies the original equation

• By solving the equation again
