SUMMARY
The quadratic expression n^2 - 14n + 40 is analyzed to determine whether it yields prime numbers for integer values of n when n ≤ 0. The discussion emphasizes the need for a formal proof to establish the primality of the expression for specific integer inputs. Participants are encouraged to explore the workings behind the proof, indicating that while calculations may be straightforward, the formal justification remains challenging. The thread is closed, but further exploration is suggested through the provided link.
