I am to solve the given polynomial equation of x^4+14x^3+14x2+14x+13=0 I am to give the solution set of this. I am to use Descartes Rule of Signs and Rational Zero Theorem. So far I have the solution set of (-1,-13,+i,) I can't put the line under my plus for +/- but please know that it is supposed to be there. I could be wrong but I am thinking this is the solution set I am to give. Does anyone have any answers on this?
