Most of the stuff here is talk of finding the factors algorithmically, but no sense of how to do so intuitively. Perhaps examples would help. <span style="font-size: smaller;" class="autosigned">— Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/140.247.79.236|140.247.79.236]] ([[User talk:140.247.79.236|talk]]) 17:30, 13 February 2012 (UTC)</span><!-- Template:Unsigned IP --> <!--Autosigned by SineBot-->
== Incorrect example ==
The current example for factorization of:
f = x^11 + 2 x^9 + 2x^8 + x^6 + x^5 + 2x^3 + 2x^2 +1
says that the result is:
f= (x+1)(x^2+1)^3(x+2)^4
But that does not seem correct:

or:
http://www.wolframalpha.com/input/?i=expand+%28x%2B1%29%28x%5E2%2B1%29%5E3%28x%2B2%29%5E4
Not sure what should be fixed: the polynomial or the factors?

:The article is correct, although the fact that the factorization is done '''modulo 3''' is not clear enough. I have clarified this. To verify correctness, you have simply to add "mod 3" at the end of the command line of each link that you have provided.
