Question

32a^3+4b^3
I was able to come up with two different answers and am not sure which one is correct.
4(8a^3+b^3) or 4(8a+b-8ab+b^2)

Answer 1

when you expand the 2nd option,do you get any a^3?

Answer 2

no I don"t think so

Answer 3

then its wrong...
remember the expanded form and the factorized form of an expression are 2 forms of the same expression
if you're not sure that you've factorized correctly,just expand
