# Triplicated question:

These questions are duplicate of each other:

What should be done?

• In my opinion: The question with no answers should be closed. One of the question has an attempt by the OP as an answer. That one should probably be merged into the one which already has an upvoted answer. (For two of them I voted to close. Only mods can merge questions - so let's wait and see what mods will answer here.) – Martin Sleziak Sep 21 '14 at 11:32
• After the close votes were cast, both question already entered the review queue: 1, 2. – Martin Sleziak Sep 21 '14 at 12:06
• The same person posted the same question three times? He should be taken out and shot. Then we can worry about what to do about the questions. – Gerry Myerson Sep 21 '14 at 13:08
• The same user has asked a different question twice: math.stackexchange.com/q/863550/18398 and math.stackexchange.com/q/858124/18398 – Joel Reyes Noche Sep 21 '14 at 13:22
