is this wrong? the fi etc are just scalars. i cannot make sense of it unless i assume fj stays being fj when we pass from line 1 to 2. If it changes to fi, the sums in line 2 and 3 do not have the same members, because you get just one member with d0, namely f0g0hn in line 2 and in line 3 you get f0*(n summands), so there are n members with f0.
this is from hoffman and kunze linear algebra chapter on polynomials.
