Some one help me? I got part A but I think I need an opinion on it.. need help with part b and c

OpenStudy (anonymous):

3x3y + 12xy - 3x2y - 12y Part A: Rewrite the expression so that the GCF is factored completely. (3 points) Part B: Rewrite the expression completely factored. Show the steps of your work. (4 points) Part C: If the two middle terms were switched so that the expression became 3x3y - 3x2y + 12xy - 12y, would the factored expression no longer be equivalent to your answer in part B? Explain your reasoning. (3 points)

ganeshie8 (ganeshie8):

what did u get for PartA ?

OpenStudy (anonymous):

3y((x^2+4)(x-1))

OpenStudy (anonymous):

i don't think it's right tho..

ganeshie8 (ganeshie8):

thats part B !

OpenStudy (anonymous):

oh okay then i need help with a and c lol

ganeshie8 (ganeshie8):

for part A, you just leave it after factoring out the GCF : \(\large 3x^3y + 12xy - 3x^2y - 12y\) GCF = 3y, factor it out : \(\large 3y(x^3 + 4x - 3x^2 - 4)\) done wid PartA

ganeshie8 (ganeshie8):

for partB, you factor the stuff inside parenthesis... and then u wud get the factored form which u had shown earlier

OpenStudy (anonymous):

gah sorry my internet messed up :(

OpenStudy (anonymous):

you still there?

OpenStudy (anonymous):

I still need help with part c
