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.
Like so:
Make sure you check this carefully to see if I've made any silly mistakes!
f1.f2.f3. = -3 ?
Oops! Quite right. I messed up that detail. The method still holds but Firebolt will need to go through it correcting the numerics.
