Final answer:
To rewrite the middle term -16n, split it into two terms with opposite signs and factor out a common factor from each term.
Step-by-step explanation:
- To rewrite the middle term -16n, we can split it into two terms with opposite signs: -8n - 8n.
 - Now, we can factor out a common factor from the first two terms: 2n(4x - 4).
 - From the last two terms, we can factor out a common factor of -8: -8(2x - 1).
 - Combining these results, we get the new expression: 2n(4x - 4) - 8(2x - 1).
