I would like to know how this question can be improved so that it can be reopened and receive further answers: https://math.stackexchange.com/questions/950520/math-problem-is-xyz-is-divisibleby-xyz
I am not the OP for that question, so it's not clear to me whether I can edit the question to add context. The comments say that the OP should show evidence of thinking about the problem. If I edit it to improve it, is it enough to show my thoughts about it? That would improve the question, but it would no longer really be his question.
If it is in fact no longer possible for someone besides the OP himself to improve the question, and someone wishes to provide an answer in addition to those already there, how should he proceed?
I was confronted with that situation, so I asked the OP's question again and answered it myself, since the FAQ says you can ask and answer your own question, here: https://math.stackexchange.com/help/self-answer . I was later told by one member that that was not the right thing to do because that duplicated the OP's question that had been closed.
I would like to clarify that I am the same person as user179549.
