Comment (by gagern):
Replying to [comment:2 gagern]:
> The division `r1/r2` for the example …
… can be used to exhibit several problems which are not directly related
to arithmetic via resultants, so I filed separate tickets about these:
* #17895 about `p.roots(QQbar)` being faster than
`QQbar.polynomial_root(p, …)`
* #17896 about the slow exactification mentioned above: still not
completed after 6h
