Set the given function equal to 300 and solve the resulting quadratic equation. The trouble is that you have a profit function that doesn't work. Perhaps you have written it incorrectly -- for example -- note the positive sign on the constant term -- has two real solutions. For the function given, the company loses money (negative profit) regardless of the value of .
