The video tutorial explains how to solve a quadratic equation by extracting roots. It begins by isolating the square term, then taking the square root of both sides, ensuring to include the plus or minus sign. The solution involves complex numbers, which are expressed in the form a plus bi. The tutorial provides a step-by-step approach to reach the final complex solutions.

What is the first step in solving a quadratic equation by extracting roots?

• Isolate the square term

• Multiply both sides by a constant

• Add a constant to both sides

• Take the square root of both sides

What operation is performed to isolate the square term in the equation?

• Adding 3

• Multiplying by 3

• Subtracting 3

• Dividing by 3

After isolating the square term, what is the next step?

• Multiply both sides by a constant

• Divide both sides by a constant

• Add a constant to both sides

• Subtract a constant from both sides

What must be included when taking the square root of both sides?

• Only the negative root

• Neither root

• Only the positive root

• Both positive and negative roots
