Please, could you explain more what is the problem. According to my understand. b and c are two parameters and you want to solve for d. and you try to use grobner basis, but what I know grobner basis for polynomial and this is not polynomial because the square root. So , you can write d=y^2, y^2==b*y+c if d is real. And if d is complex, d=-y^2, -y^2==i*b*y+c.
