| Mar 24, 2010 at 20:14 | comment | added | darij grinberg | Thanks, I found the flaw in my proof. It is now fixed to work for the case when $f$ has leading coefficient $1$. The assumptions on $g$ are pretty generic. | |

| Mar 24, 2010 at 18:37 | comment | added | Sergei Ivanov | This argument works for $f(x)=x+const$, the case $f(x)=ax+b$ where $a\ne 1$ is different. | |
| Mar 24, 2010 at 18:33 | comment | added | Aeryk | This seems to do the trick for my case: Thanks! I don't know if I'm convinced this will work for "uglier" polynomials in $Z[x]$, like say $f(x)=x+7$ and $g(x)=x^2+3x+9$ ... | |
