Factorize:
$2011^4+ 7. 2011-12$
Can everyone share techniques for Factorization?

Re: Can u Factorize?
Well the equation given here has a nasty factorization of $2*79*25583*4046129$ (google "prime factorization calculator" or download the attachment). Though I think $2011^4- 7. 2011+12$ has a nice one
($2.2.2.2.2.2.2.2.2.3.7.19.113.708479$). So I think the problem should be corrected.

$a^4+7a-12=(a^2+a-3)(a^2-a+4)$

I think this is a number theory problem. Please inform me if I'm wrong.

Okay I'm giving it again in another extension. Unzip it with any extracting software (winrar,7zip or winzip) and open the HTML file.
