Homework Equations
The Attempt at a Solution
I worked through it and I ended up with (l=lamda) l^3-.9l^2+.54l-.162=0
With my calculator I found one of the values, which means that there are 2 complex values.
Considering how I have not done this in a while, how do I find the complex roots of this equation?
Thanks in advance
