YES, it can be factored more. The way to see this is that (x^3 - 27) has the obvious root x = 3. That being the case, (x-3) must divide into it.

In the end, it should be:

3x^4(x-3)(x^2 + 3x + 9)

Of course you can! (x^3 - 27) is (x^3 - 3^3) so it is divisible by (x-3).

No you factored it as far as it can go.
