Question

Kylie explained that will result in a difference of squares because . Which statement best describes Kylie’s explanation? Kylie is correct. Kylie correctly understood that it is a difference of squares, but she did not determine the product correctly. Kylie did not understand that this is a perfect square trinomial, and she did not determine the product correctly. Kylie determined the product correctly, but she did not understand that this is a perfect square trinomial.

Answer 1

Answer:

Option 3

Step-by-step explanation:

Our question is: Kylie explained that will result in a difference of squares because.

Our aim is to find which statement best describes Kylie’s explanation.

The following expression, (-4x + 9)^2, is not equal to (-4x)^2 + 9^2 because it is actually equal to the product of two factors (3 + 2sqrt x) (3- 2 sqrt x)

We can not use distributive rule here, and therefore it is not correct.

Hence we can conclude that our correct option for this problem will be the third one, because Kylie did not understand both perfect square trinomial and did not determine the product  correctly.
