The Attempt at a Solution


I really don't know where to start. There is nothing given for me to start with. And the instruction says "Choose" so am I really suppose to really choose or do you guys any idea how to start this?

*I know that eigenvalues have to negative

I suspect that the reason for the word "choose" is that there are an infinite number of solutions. For example, a "trivial" solution is C_1= C_2= 0 and \lambda_1 and \lambda_2 can be anything. If C_1 and C_2 are not both 0, then it is a little more interesting. What can you say about the limit of e^{\lambda t} as t goes to 0? Look at \lambda> 0 and \lambda< 0.
 
all i can say is that lambda has to be negative for it to go 0 right?
 
Yes.
 
so i can pick any negative integer number for lambda and any integer for C1 and C2?
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
