A cubic polynomial has the form p(z)=z^3+bz^2+cz+d, z is Complex and b, c, d are Real. Given that a solution of p(z)=0 is z1=3-2i and that p(-2)=0, find the values of b, c and d.

I will explain this choice of question and demonstrate my approach of showing the most forward way to solve this in the interview.
