What is the product?

 $3x\left(x^2+4\right)$  

•  $x^2+3x+4$  

•  $3x^3+4$  

•  $3x^3+12x$  

•  $3x^2+12x$  

What are the values for A, B, and C?

Did Cherise use algebra tiles to correctly represent the product of (x - 2)(2 - 3)?

• No, she did not multiply the x-tiles by the negative integer tiles correctly.

• No, she did not multiply the negative integer tiles by the other negative integer tiles correctly.

• No, she did not add the terms together correctly.

• Yes, the product is x² - 5x - 6.

Which equals the product of (x - 3)(2x + 1)

• $2x^2\ -\ 7x\ -\ 3$

• $2x^2\ -\ 5x\ -\ 3$

• $3x\ -\ 2$

• $6x^2$

Find the product of (–d + e)(4e + d). Which statements are true? Check all that apply.

• There are 2 terms in the product.

• There are 3 terms in the product.

• There are 4 terms in the product.

• The product is degree 1.

• The product is degree 2.

What is the product of the binomials (4a - 1) and (2b + 3)?

• $18ab\ -\ 3$

• $8a^2b^2+10ab-3$

• $6ab+7a-2b-3$

• $8ab+12a-2b-3$

Which products result in a difference of squares or a perfect square trinomial? Check all that apply.

• (5x + 3)(5x - 3)

• (7x + 4)(7x + 4)

• (2x + 1)(x + 2)

• (x - 9)(x - 9)

• (-3x - 6)(-3x + 6)

Which expressions can represent the length and width of the garden?

• length = x² - 3 ft; width = 2 feet

• length = 2x + 3 ft; width = x - 2 feet

• length = 2x + 2 ft; width = x - 3 feet

• length = 2x - 3 ft; width = x + 2 feet

Louise completed the work shown below. Is she correct?

 $\left(5x^3+3\right)^2=\left(5x^3\right)^2+\left(3\right)^2\ =\ 25x^6\ +\ 9$  

• Yes, she is correct. She squared both terms correctly. 

• No, she is not correct. She did not square the first term correctly. 

• No, she is not correct. She did not square the second term correctly. 

• No, she is not correct.  She needed to multiply the product  $\left(5x^3+3\right)\left(5x^3+3\right)=25x^6+30x^3+9$
