1, what is a simpler form of the expression (2n^2+3n+3)(4n-5)
OpenStudy (dmezzullo):
Put the like terms together to start.
OpenStudy (genralduck):
so 3n and 4n become 7n?
OpenStudy (dmezzullo):
I believe they'd be multiplied because they're in parentheses.

ok so they become 12n
rebeccaxhawaii (rebeccaxhawaii):
you would foil except you have more terms
OpenStudy (dmezzullo):
Right 12n, then do the negative terms.
OpenStudy (genralduck):
the only negative term i see is the -5
OpenStudy (dmezzullo):
My bad multiply the -5 by the positive 3.

ok then you have -15
OpenStudy (dmezzullo):
Then there's nothing else you can do so put them in parentheses and there's the answer.
OpenStudy (genralduck):
ok so the answer is (2n^2+12n-15)?
OpenStudy (dmezzullo):
Correct because there's nothing else you can put together because nothing else has like terms.
OpenStudy (genralduck):
ok, thanks for the help, here's a medal
