Don't answer if you don't know it if you say sorry i don't know it i will report you Determine whether 81a^2 − 25z^6 is a difference of two squares. If so, factor it. If not, explain why.
(9a + 5z^3)(9a − 5z^3)
(9a − 5z^3)(9a − 5z^3)
It is not a difference of squares because −25z^6 is not a perfect square.
(9a − 5z^6)(9a + 5z^6)
