For college beginning algebra.
~Please explain every step because I'm mathmatically stupid~
The answer is SUPPOSIDLY 5(K+2)(K^2-2K+4)
but i dont see how they get it.
Here's the example they put in the book for this type of problem.
64x^3 + 1
(4x)^3 + 1^3
and so from what im takin it is..
if you have
Then first step is.. you gotta make the 40 into a cubed like the 5k^3..
but.. as far as i know, NOTHING cubed is 40. I had my dad look at this too and he has no idea what to do.. and neither do i.
