@NajibIdrissi The point is, 10K+ users should know better than to answer yet another quadratic equation question. We already have excellent answers explaining the general method. Adding an answer, and reopening/undeleting the question (potentially to preserve reputation) is not a positive contribution to the site.

@NajibIdrissi And the undeletions happened by the same group of three. I don't know if this counts as some sort of conflict of interest.

comment What is going on with undeletion lately?
Such questions should be closed as abstract duplicates of answers that explain the general method. We cannot afford to have a question with specific solutions for every quadratic equation out there. Such questions add zero value to the site and make it more difficult to find interesting questions. That said, we have no such consensus in the community, and some users want to continue to answer such zero value questions and undelete them when they get deleted.

@BalarkaSen Not in general, no. See this.

comment Question related to the definition of affine schemes
No, the definition only requires the induced map on global sections to be an isomorphism. It does not have to be the identity.
