Garage Floor

Hello, I want to fix up my garage floor which has alot of cracks in it, and just wondering the best way to go about patching them up. Can i just use a patching cement for them even though some are pretty deep, or do i have to use something special for the deep cracks. :) Attachment 37504 (http://www.doityourself.com/forum/attachments/garages-garage-door-openers-work-shops-sheds-breezeways-carports/37504-garage-floor-dscn7869.jpg)
