You did not specify which device you are using, but, you should be able to go into Settings > Applications > All.
Usually, you cannot delete most of the pre-installed applications, but, you can force stop them or turn them off.
When you go into your "All" application setting, tap on the application name you want to disable and choose an option (probably "Turn Off", if possible, or "Force Stop" if there is no option to turn the application off).
