Homework Statement
Hey!
I don't really face a problem at the moment but i'd like someone to act as another brain for me. I've solved - hopefully right - a quartic equation and i get all the 4 roots out but 2 of them turn out to be complex numbers. Now, I'm fine with that but i'd also need to solve quartic inequality with the same polynomial. At the moment I'm not sure how i'd go about it with complex numbers so i'd love it if one of you checked the following and would confirm that the quartic really has complex roots.
