Solve a quadratic by applying the square root method

The video tutorial explains how to solve equations using the square root method. It begins by setting the equation to zero and using inverse operations to simplify it. The process involves taking the square root of a fraction and ensuring to include both positive and negative solutions. The tutorial concludes with a summary of the steps involved in the square root method.

What is the first step in solving an equation using the square root method?

• Set the equation equal to zero

• Subtract a constant from both sides

• Multiply both sides by a constant

• Add a constant to both sides

Which operation is used to counteract multiplication by a number in an equation?

• Addition

• Subtraction

• Division

• Multiplication

When taking the square root of a fraction, how can it be simplified?

• By adding the numerator and denominator

• By multiplying the numerator and denominator

• By taking the square root of the numerator and denominator separately

• By subtracting the numerator from the denominator

What must be included when introducing the square root in an equation?

• Only the positive root

• Only the negative root

• Both positive and negative roots

• Neither positive nor negative roots

What is the final expression for X when solving the equation using the square root method?

• X = sqrt(5) / 6

• X = ± sqrt(5) / 6

• X = 5 / sqrt(36)

• X = ± 5 / 6
