Question 113943: I have one more question I need help with. I need to prove that the polynomial P(x)=x^3-3x^2-5 must have complex roots without using a graph and explain what rule can be used. I answered Descartes rule but my instructor is asking me to explain what this shows and what conclusion I can draw knowing number of roots for a cubic. This section has been a little tough for me. Any help would be much appreciated.
Thank you,
