yes
myininaya (myininaya):
it looks like they have 24 in common too
OpenStudy (anonymous):

24p^2(p-3) is what we get looking at the first 2 terms

OpenStudy (anonymous):
32
myininaya (myininaya):
what happens if you factor out a -32 out of the second two
OpenStudy (anonymous):
-32 (p + 3) ? im not sure
myininaya (myininaya):
you get -32(p-3)

o okay
myininaya (myininaya):
so we have 24p^2(p-3)-32(p-3)
OpenStudy (anonymous):
yea
myininaya (myininaya):
so we have terms and they both have p-3 in common so we can factor out a p-3
myininaya (myininaya):
two terms*

o okay
myininaya (myininaya):
(p-3)(24p^2-32)
OpenStudy (anonymous):
and then i factor out an 8?
myininaya (myininaya):
If you want to factor completely, you could look at the second factor and factor out this 8 you are talking about. so we have 8(p-3)(3p^2-4)
myininaya (myininaya):
finished!
