Abstract
There is a question attributed to Irving Kaplansky concerning the solvability of the quadratic equation x2−py2=a in the case that the prime p=a2+(2b)2. This question was answered in the affirmative by Mollin [1], although according to [3], this result is implicit in the work of Gauss and Legendre. The proof appearing in [1] was later simplified in [4], and it was also shown therein that Kaplansky’s question was a special case of a more general result. Using the method of proof in [4], Mollin [2] has recently extended the results of [4], but upon further consideration, it appears that there is a more general phenomenon occurring, and also, that one of the assumptions in the main theorem of [2] is unnecessary. In this paper we prove this generalization, and eliminate one of the assumptions stated in the main result of [2]. The proof is again based on the method described in [4].

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
