Go to https://www.facebook.com/help/delete_account/. Keep in mind that you cannot do this in the Facebook mobile app. If prompted, type your email address into the "Email" text field, type your Facebook password into the "Password" text field, and click Log In. This option is below the warning message in the middle of the page. Clicking it brings up a pop-up window. Type your password into the "Password" field at the top of the window. This code is the jumble of letters and numbers in the middle of the window; you'll type your answer into the field below the code. If you can't read the code, you can click either the Try another text or the an audio captcha link below the code to generate a new one. This will submit your code. If it's correct, another pop-up window will appear. If you incorrectly entered your password or captcha code, you'll be asked to try again. It's at the bottom of the pop-up window. This will deactivate your account for 14 days, after which point the account will be deleted.
