Answer 1

[John D'Errico]

So why not use roots? What are the coefficients of that cubic polynomial? Don't forget to use zeros where appropriate. Or if you prefer symbolic form, then why not use solve?

This is YOUR homework. Think about what is being asked for, and then look for the solution. These are virtually one liners.
