# Homework Help: Factoring

Posted by Ben on Sunday, November 25, 2007 at 7:20pm.

How do I factor
-3p^2+66p+9

• Factoring - bobpursley, Sunday, November 25, 2007 at 7:25pm

see my other post. On this one, divide out the factor 3 first.

I took out the three to get 3(-p^2+31) but my answer is not making any sense with the question I am being asked because of my p value must be between 18 and 28. HELP

Is this a different problem? You should be factoring -3p^2+84p-288 if it's the same one as before.

Start by taking out a common -3.

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

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