I understand some calculators can solve for cubic equations I’m not sure if yours can but otherwise you just use factor theorem and T&E values of H.
This particular question is quite tricky cause will only find 2 roots since one of them is repeated root.
So have to prove that one of the roots are repeated or can use either (h+1) or (h-2) for Long division.
