I've heard there's a proof out there of this, basically that (I think) you can use the intermediate value theorem to prove that an Nth-degree polynomial has no more than N roots.(adsbygoogle = window.adsbygoogle || []).push({});

I'm not in school anymore, just an interested engineer. Does anyone know where I can find this proof or any reallystronghints on how to do it myself? I've been out of it for a while and I'm rusty.
