We have 3⁴ = 81, so we can factorize this as a difference of squares twice:

Depending on the precise definition of "completely" in this context, you can go a bit further and factorize
as yet another difference of squares:

And if you're working over the field of complex numbers, you can go even further. For instance,

But I think you'd be fine stopping at the first result,
