Divide using long division or synthetic division.
(21x^3  7)/(3x  1)
This is what I have so far, but I am having a hard time with what to do next.
3x1/ 7(3x^31)

Reiny,
horrible division!
it is hard to show long division on here, but the answer I got was
(21x^3  7)/(3x  1) = (7x^2 + (7/3)x + 7/9)  56/(9(3x1))
