How to Solving a Radical Expression with a Variable on Both Sides

The video tutorial covers complex numbers and basic operations like addition, subtraction, multiplication, and division. It then moves on to solving equations involving square roots by squaring both sides to eliminate the square root. The tutorial explains how to isolate variables and solve for X, emphasizing the importance of understanding operations such as addition and subtraction. Finally, it demonstrates how to verify solutions by plugging them back into the original equations to ensure correctness.

What is the first step in solving an equation that involves a square root?

• Add a constant to both sides

• Multiply both sides by a constant

• Square both sides

• Divide both sides by a constant

When solving the equation X + 4 = 3X, what should you do to isolate X?

• Divide both sides by 3

• Multiply both sides by 3

• Subtract X from both sides

• Add 4 to both sides

If you have 3X - X, what is the simplified form?

• 0

• X

• 2X

• 4X

What is the final value of X in the equation X + 4 = 3X?

• X = 0

• X = 6

• X = 2

• X = 4

Why is it important to substitute the solution back into the original equation?

• To verify the solution is correct

• To find a different solution

• To eliminate any constants

• To simplify the equation further
