This QuestionQuestion, about how many real roots a (real) quartic equation has, was closed as "off-topic" qua not about mathematics.

The OP is not a native English speaker, but based on clarifying comments, I have undertaken to rewrite the Question, disposing of distracting elements that may have induced much of the votes to close earlier.

Please consider voting to reopen. The OP mentions discriminants, which is one of several possible approaches, and in my opinion shows sufficient context for the Question to be taken seriously by the Community.
