How to bribe the Professor?

I have Professor Pestor keep showing up and ruining everything, the guide all say bribe him. But I have no idea how. There are not video on youtube even - they all have cheats.

I know it SHOULD be easy, but I haven't found anything about it at all. I don't want to use cheats and glitches, but how do I bribe him so he goes away?

Thanks.

Bribing & pickpocketing =$$$

Been doing this pretty steady for the past two days an I am sky rocketing my speech by bribe the guards then pickpocketing then the bribe $$ right back again, the pickpocket goes up quicker almost a whole level every time, and my speech moves up a level
every other bribe at a $289 cost per bribe, that I pick pocket back right after, just make sure you do a quick save before pickpocketing.. easiest places to do this is windhelm,solitude, an white run, just make sure you get caught just once an then let the
bribes begin, found this kind of harder to do with a higher pickpocketing skill so you might want to go to these three areas get caught an then just make your rounds..THE HIGHER YOUR SPEECH EQUAL$ BETTER PRICES @ MARKET$
