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)...
