You can use the "roots" function to find the roots of a polynomial, . Since the equation in the question is not clear, lets assume that you wish to find the roots for the polynomial 
.
.% Define the coefficients of the polynomial
coefficients = [13, -182, 184, -2503];
% Calculate the roots of the polynomial
roots_of_polynomial = roots(coefficients);
% Display the results
disp(roots_of_polynomial);
