  3. Yes, the quadratic formula is a way of solving for x (or p in this case).

    The Quadratic Formula states that for any equation ax^2 + bx + c...
    x = -b +- √(b^2 - 4ac) all over 2a.

    Identify your a, b, and c, and then plug and chug.

  4. I got -22.13552873 and -.1355287257...is this right? It does not make any sense though because this should be a price charged to obtain the largest revenue

  5. Your 22... should be positive. Check your work for a sign error.

    The +- means plus or minus. (You'll always have two answers.)
