This video tutorial teaches how to solve quadratic equations by factoring. It begins with a review of the zero product property and factors, followed by common mistakes to avoid, such as not setting the equation to zero. The tutorial includes two examples demonstrating the factoring process, emphasizing the importance of checking solutions.

What does the zero product property state?

• 0 times anything is 1

• 0 times anything is 0

• 1 times anything is 1

• 1 times anything is 0

Which of the following is a common mistake when factoring quadratic equations?

• Setting the equation equal to 0

• Setting the equation equal to 10

• Using the zero product property

• Identifying all factors

In the equation 2x^2 + 4x = 0, what is the greatest common factor?

• x

• 2

• 2x

• 4x

What are the solutions to the equation 2x^2 + 4x = 0 after factoring?

• x = 2 and x = -2

• x = 0 and x = -2

• x = 0 and x = 2

• x = 1 and x = -1

In the second example, what is the first step in factoring the equation?

• Use the zero product property

• Solve for x

• Identify the greatest common factor

• Set the equation equal to 10

What are the solutions to the equation after factoring in the second example?

• x = 7 and x = -5

• x = -7 and x = 5

• x = 5 and x = -5

• x = 7 and x = 5

Why can't 3 be a solution in the second example?

• Because 3 is not a factor

• Because 3 is not equal to 0

• Because 3 is equal to 0

• Because 3 is a factor
