    Dr Keister,
    I have a question about the Chapter 9 test. On problem 16.) -12r^2+5r+3 I've got 8 and 3 ( You subtract 8-3 and you get 5)
    -12(r+8)(r+3) but.. when checked this is what I get r^2+11r+24 then when I multiply by -12 it equals (-12r^2-132-288)

    I see you removed my post on P vs. NP. I ask you to allow this. There is no way to present this if not on free forums. I also prefer scientific publication, but such one is impossible...

    Hi Ackbach,
    I was just wondering, is it ok to post a thread about my questionnaire for research for my sixth form project? The post would just be a link to the questionnaire page with a short description on what it is. It's maths related, more specifically history of maths, and my target group are under and postgrads in maths. I know some maths forums only want posts relating to maths problems and get annoyed if you post anything else, so I just wanted to know if this is ok and if it is then which sub-forum I should post it under.
