I am trying to find the solution of 5 degree equation symbolically but not getting the desired solution. I have written the following code:
dbstop if error
clear all
clc
syms b c d h A
Z=1+b^2*c^2+2*b*c-(b-c)*d*(1+b*c)-(((c+h)/(1-c*h))-b)*(b-c+d+b*c*d)-(1+b^2)*(1+b*c)*(d+d*b*c+b-c)-((A*(d+((b-c)/(1+b*c)))*(1+b^2)*(1+b*c)^2)/(1-A*b))
solve(Z,b,'MaxDegree',5)

Use a numerical solver (e.g. MATLAB's "roots" after multiplying your equation by the denominators).

What is the desired solution? Do you have evidence that it can be factorized ?
