    Here is the solution for your problem. Explanation: I found a root with trail and error that is x equals to 1 and next by using synthetic division I found the quadratic equation ( if you multiply this quadratic equation with x-1 you will get the cubic equation given in the question) , Then simple using Discriminant I found the nature of roots of quadratic equation (complex since discriminant is less than 0) . Finally we have one real root and two complex roots. Hope this helps you.
