is that \[\huge 75n+3n^3\]
OpenStudy (anonymous):
yes
OpenStudy (anonymous):
factor out 3n
OpenStudy (anonymous):
how do I facor with 3n^3??
OpenStudy (anonymous):
ask your self what happens when you divide the expression by 3n
whats left???

um n?
OpenStudy (anonymous):
3n( + )
OpenStudy (anonymous):
3n(?+?)=
OpenStudy (anonymous):
the problem asks for a format like this: ___n^__(n^__ + ___) if this helps us any

yes we start by factoring 3n first then get to that form
1st you shud try to do this 1st

OpenStudy (anonymous):
3n(25n + n) is that right?
OpenStudy (anonymous):
@kljasdjasdl why are you giving me a picture that has to do with angles?
OpenStudy (anonymous):
3n(25+n^2) right dont forget n^2

OpenStudy (anonymous):
also 25 without n
OpenStudy (anonymous):
oh, now I get it. divide 3n^3 by 3n and you lose one 3n
OpenStudy (anonymous):
@kljasdjasdl use \[s=r\theta\]
\[3/4\pi=4\theta\]
OpenStudy (anonymous):
yes @craftshark98 correct
OpenStudy (anonymous):
we know have \[\huge{3n(25+n^2)}\]
here we can ongly
here theres nothing more we can do than write complex factors

are you sure the problem is not 75n-3n^3 but 75n+3n^3
OpenStudy (anonymous):
is it + or -
OpenStudy (anonymous):
I'm pretty sure it's an addition sign. I'm looking right at it.
