Question: Show work for BLS12-381 Fq12 modulus

I'm learning more about bls12-381 and currently stumped by one part of the code:
I'm assuming that
```python3
FQ12_modulus_coeffs = (2, 0, 0, 0, 0, 0, -2, 0, 0, 0, 0, 0) # Implied + [1]
```
means x¹² -2x⁶+2
and that it is the irreducable polynomial used as a modulus for F_q¹².

I feel like this had to be from the specification https://github.com/zkcrypto/pairing/tree/master/src/bls12_381#bls12-381-instantiation , but I don't see how it was done.

I feel pretty dense with this one, but I'm hoping that someone more knowledgable can show the work on how the above polynomial was created.
