    Continuing to post the same problem over and over doesn't help anything. (and is against the Forum Rules at that.) I'm closing all but this thread.

    Show us what you've done or attempted. That's how we can help you best.

    Re: Need help with a tough problem

    I would imagine that you first need to find the quadratic function that represents the profit. The question tells you how to do this: $$P(x) = -2x^2+28x-26 = -2(x^2-14x+13)$$
    Then, by transforming this into the vertex form of the quadratic function, you will be able to read off the answers to points 2 and 3 (don't forget that factor of $-2$ affects one of these answers). Point 4 is just the evaluation of the price function given in the question at the appropriate value of $x$.
    Point 5 requires you to factorise the quadratic function, specifically the part in parenthesis above.

    There are other ways to go about this problem.
