The polynomial f(x)=x3+x2+2x+3 has three distinct roots. Let  g(x)=x3+bx2+cx+d be a cubic polynomial with leading coefficient 1 such that the roots of g(x) are the squares of the roots of f(x). Find the ordered triple (b,c,d).

Thanks in advance.

Make sure you check this carefully to see if I've made any silly mistakes!

Oops!  Quite right.  I messed up that detail.  The method still holds but Firebolt will need to go through it correcting the numerics.
