Question

Question 1) Ricky and Tom are doing math together.

1a) Rick thinks this is perfect square trinomial. Tom thinks this is a difference of two squares. Who is correct?

[x² + 8x + 16] · [x² – 8x + 16] = (x² – 16)²

1b)  Rick thinks this is perfect square trinomial. Tom thinks this is a difference of two squares because the first term is negative. Who is correct? Why or why not?

–9x² – 30x – 25

1c) Is this the product of a perfect square trinomial? Tom says it is, Rick says it's not. Who is correct?

(y + 4)² – 2(y + 4) + 1

1d) Rick says it's a difference of two squares. Tom says it's not, because of the exponent n. Who is correct?

x²ⁿ – y²ⁿ
