How to take out carpet
Decide the final goal of your remodeling.
Do you want to save what's underneath the carpet? Some older houses have ugly, old carpet right over hardwood floors. Pull up a corner of the carpet and see what's underneath if you haven't yet.
Will you put down new carpet, or hire someone to do so? If so, you may wish to leave the tack strips in place if they are in good condition. Ask the installers you will hire what they prefer.
