    Please substitute x = -3 and, after a little algebra, display the result.

    I agree it was a simple mistake, but I don't agree that it isn't troubling that several people made the same "simple mistake". I think it is important to give correct answers when helping people. Too many OpenStudy posters seem to be racing to give an answer before anyone else, and there are too many "simple mistakes" from people who clearly know better.
