How to get symbolic eigen values for 5x5 symbolic matrix

Hi all,

I want to get the eigen values of 5x5 symbolic matrix. I am using the code

clc;
clear all;
syms r c co l1 l2 vd e kp ki
syms s m h ce cep %a5 a4 a3 a2 a1 a0
%syms g r c co l1 l2 vd e s m h ce cep ...
%syms kp s m h

m(1,1)= 0;
m(1,2)= 0;
m(1,3)= vpa(-2*e/(l1*(vd+e)));
m(1,4)= vpa(-kp*(vd+e)/(2*l1));
m(1,5)= vpa(-(vd+e)/(2*l1));

m(2,1)= 0;
m(2,2)= 0;
m(2,3)= vpa(2*vd/(l2*(vd+e)));
m(2,4)= vpa(-(kp*(vd+e)+2)/(2*l2));
m(2,5)= vpa(-(vd+e)/(2*l2));

m(3,1)= vpa(e/(c*(vd+e)));
m(3,2)= vpa(-vd/(c*(vd+e)));
m(3,3)=0;
m(3,4)= ( kp*vd*(vd+e)/(2*c*r*e) );
m(3,5)= vpa( vd*(vd+e) / (2*r*c*e));

m(4,1)= 0;
m(4,2)= vpa(1/co);
m(4,3)= 0;
m(4,4)= vpa(-1/(r*co));
m(4,5)= 0;

m(5,1)= 0;
m(5,2)= 0;
m(5,3)= 0;
m(5,4)= vpa(ki);
m(5,5)= 0;

eig(m)

- and getting the answers as

Rootsof(...Some big expression...) Can anyone please suggest me,how can I get exact eigen values
