Welcome to Android Central! The only way to actually remove bloatware requires rooting your phone. If you'd rather not do that, then you can Disable most bloatware apps by going to the App Manager, selecting the app, and tapping "Disable" (or "Turn Off"). This will prevent the app from opening (and hence prevent it from occupying any active RAM), hide it from the App Drawer, and prevent any updates. It will not, however, uninstall it, so the actual storage space required for it the app will still be taken up.
