How to solve a quadratic by using the square root method

The video tutorial explains how to solve an equation using the square root method. It begins by discussing the problem and potential methods, then demonstrates the step-by-step application of the square root method. The solution is simplified, considering both positive and negative roots, and concludes with a summary of the process.

Why can't the difference of two squares method be applied to the given problem?

• Because the equation has no real solutions

• Because the equation is already simplified

• Because the equation is not a polynomial

• Because 6 and 2/3 are not squared numbers

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

• Take the square root of both sides

• Simplify the equation

• Add to both sides to eliminate subtraction

• Multiply both sides by the reciprocal

How do you eliminate the fraction in the equation?

• By dividing both sides by the fraction

• By multiplying by the reciprocal on both sides

• By subtracting the fraction from both sides

• By adding the same number to both sides

What must be considered when taking the square root of both sides of an equation?

• Neither positive nor negative values

• Both positive and negative values

• Only the negative value

• Only the positive value

What is the simplified form of sqrt(18) in the context of this problem?

• sqrt(36)

• 3 sqrt(2)

• 2 sqrt(9)

• 9 sqrt(2)
