yup. I've gotten to where it is
(x+27)(x^2 - (x times 27))+ 27^2
ah, because 3 x 3 x 3= 27
So if it was, x^4 - 16 it would be x^4 - 2^4 just as an example to see if i understand.
i'd put that over x-3, but cancel out the x-3 since it is in both the numer. and denom. therefore leaving me with
i may have done the part wrong, or it isn't simplified enough
difference of cubes before the next test! (Wink)
