WebNov 13, 2015 · I have a polynomial of the form: s^3+7s^2+10s+K I want to find the three roots in the form r=a+bK+ (c+dK)i I tried using K as a symbolic variable, but then "roots" gave really long solutions. is there any way of simplifying the solutions of roots (double (ans) is not an option since K is a sym)? Thanks a lot! 0 Comments Sign in to comment. WebApr 7, 2024 · You won't succeed in this generality. To determine the eigenvalues, MATLAB had to solve for the roots of a polynomial of degree 13 with symbolic coefficients. This is in general only possible for polynomials up to degree 4.
