So what is the fundamental theorem of algebra? Perhaps this Khan Academy short video will help things along. https://www.khanacademy.org/math/algebra2/polynomial-functions/fundamental-theorem-of-algebra/v/fundamental-theorem-of-algebra-intro The questions are very general so I think they are designed to get you to think about the concepts. There is no real strategy to answering the questions, but it is rather to engage you in the process of assimilating the information.
