First, I'd like to appologize if this similar questions were already made. I've tried to look for something similar and the nearest I found was this. I've even looked the two examples given in the mentioned question but didn't find them too similar to my own: In my case, I guess the question is different due to the intentions of both askers.
Recently, I've made this question which was voted to close as a duplicate of this other question. In my question, I gave every information in my trial to answer and it was quite correct, I missed only the condition $x>0$ which was pointed by some users. In the second question, the user had a very faint approach to solving it. I knew beforehand that I could use the search (this must be a classic problem in the beginning of the study of inequalities), but I was more interested to show my work and receive criticism for it than to find an answer to it.
I feel like my question is like "is my answer correct?" with a subtle sense of correctness (I've read in the earlier pages of Courant's book that $x^2 +1\geq 2x$ and this was due to a property of the quadratic function so I knew it depended on it) and his question is "how can I do it?" with no clue on how to do it.
So are they really duplicates? This is important to me because I do a lot of this kind of questions in which I'm interested in showing what I thought - which - at least for me, seems a totally different kind of intention and hence, of question.
