What should you watch before this video to understand the box method?

• A video on division rules

• A video on subtraction rules

• A video on exponent rules and multiplication

• A video on addition rules

What is the first step in the box method for multiplying polynomials?

• Adding the coefficients

• Writing the binomials

• Drawing the box

• Combining like terms

Where do you write the first binomial in the box method?

• Inside the box

• On the top edge of the box

• On the bottom edge of the box

• On the left side of the box

What do you do after filling in the boxes with products in the box method?

• Subtract the terms

• Divide the terms

• Combine like terms

• Multiply the terms again

In the second example, what is the product of 3x and x?

• 3

• x^2

• 3x^2

• 3x

What is the final expression for the second example problem?

• 3x^2 - 2x - 8

• 3x^2 + 2x + 8

• 3x^2 + 2x - 8

• 3x^2 - 2x + 8

In the third example, what is the product of 4a and 2a?

• 6a^2

• 8a^2

• 6a

• 8a

What is the final expression for the third example problem?

• 8a^2 + 46a + 45

• 8a^2 - 46a - 45

• 8a^2 - 46a + 45

• 8a^2 + 46a - 45

How do you adjust the box method for larger polynomials?

• Use fewer boxes

• Use more boxes

• Use the same number of boxes

• Change the shape of the box

What is the final expression for the challenge problem?

• 12x^3 - 8x^2 - 45x - 25

• 12x^3 + 8x^2 - 45x - 25

• 12x^3 - 8x^2 - 45x + 25

• 12x^3 - 8x^2 + 45x - 25
