Find the minimal polynomial with root 21/3 + 21/2.
I would just use maple but I do not have it installed on this machine.
I found the polynomial and verified that this is indeed a root. I only have Eisenstiens criterion for determining whether it is irreducible, and I can not apply it in this case. Do you have another method? I have not tried substituting x=x+1 or x=x-1 or other substitutions.
The polynomial is x6-6x4-4x3+12x2-24x-4
