Answered by Ben !!!HELP!!!
how would I go about doing it and would it give me the answer for p?
Answered by Michael
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.

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
Answered by Michael
Your 22... should be positive. Check your work for a sign error.

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