Exactly.. with #1 and #2 being the biggest ones.
Move your subject away from the background and turn your lights so they don't light it directly. As long as the background is 2 or more stops under your subject, it will appear black.
Take this shot for instance..

This was shot without a backdrop at all.. the black behind her is her living room.. I just made sure that the light in there was more than 2 stops under the light on her.. and like magic, the background is black.
