This should do it

R = PolynomialRing(GF(17), 'x')
x = R.gens()[0]
y = PolynomialRing(R, 'y').gens()[0]
f =  9*y^6 - 9*x^2*y^5 - 18*x^3*y^4 - 9*x^5*y^4 + 9*x^6*y^2 + 9*x^7*y^3 + 18*x^8*y^2 - 9*x^11
f.factor()

Unfortunately, it seems that the functionality to factor over a generic polynomial ring is not implemented.

check out http://aleph.sagemath.org It implements a simple communication protocol with 'evaluate' and 'get' requests only. There is no state saved in between evaluations. You can figure out the protocol from the JS code. It's as minimalistic as possible.

The service at sagemath is experimental (we used it for testing mainly). That means it might go down in the feature. However, you can get the server code from http://code.google.com/p/sage-aleph/ and run a similar service on your own server (even implement state if you need it).

I should add that I got the sound file from http://www.freesound.org/samplesViewSingle.php?id=91968 Somebody with license knowledge should determine if we can bundle the any of the sounds on that website with Sage. Also some jquery magic should be added to remove the audio tag after it plays.

You can try this on any new browser.

def done():
    return html('!audio src="http://www.radokirov.com/gong.ogg" autoplay> Your browser does not support the audio element. !/audio>')

for i in range(10**6):
    pass
done()

Replace ! with < . I could not make the code display otherwise.

In the future a function "done()" along with a sound file can be a part of the notebook. I will remove the .ogg file from my server in the future to prevent too much hotlinking (so don't freak out if this doesn't work).
