I got 20755 when I plugged 24 in and -685 when I plugged 4 in, is this correct?

This is for -3p^2+84p-288, but I am also stuck on the other problem

I didn't think you were going to answer the other question. Now I have -3(p^2-28p+96) I am now stuck I eventually need this to be set to equal zero

How do I factor -3p^2+84p-288
*November 25, 2007*

**Calc**

No, But should I charge $24 to get the largest weekly profit?
*November 25, 2007*

**Calc**

So is it -3(p-24)(p+4) I have to find which will give me my largest profit so I need to set them equal to zero. That would then be $24, right? How do I determine max possible weekly profit?
*November 25, 2007*

**Calc**

Wait, the other one is wrong, it is -3(p-24)(p-4). So the max possible weekly profit is $24 dollars??? Now how do I determine the max possible weekly profit and be certain the profit is maximized?
*November 25, 2007*

**Calc**

I got -3(p^2-28p+96) Now How do I factor this further I need to eventually set it equal to zero
*November 25, 2007*

**Calc**

That is wrong too Now I got -3p^2+84p-288 Is this right, I cannot figure out how to factor it though
*November 25, 2007*

**Calc**

I made a mistake it should be -296 but I do not think this is right because I know I am supposed to factor this and I cannot get it to factor.
*November 25, 2007*

I got -3p^2+84p+298 Is this right?

We did what Matt said but we do not know what to do next, our teacher told us to set the derivative equal to zero and then factor to get more than one answer and say which one maximizes the profit but we cannot solve P'=0

**Calc**

I am confused on how you did the cost part. I think I got P' but I don't see this in your work. I know I have to set P' equal to zero but I don't know if I have to factor or something first
