$\displaystyle \frac{16x^5}{4x} + \frac{2x^4}{4x} + \frac{x^3}{4x}$

finish by dividing each term ...

so the answer is 4x^4+1/2x^3+x^2? Sorry to not understand.
How would I do this long division style?

I get it now sorry for being stupid.
Another question please with this one.

4x^3(2x^4+8x^3+12x^3)

I get x/2+2+3/x but my book says the answer is x/2+2(3/x) is it the same thing or?

is this a division problem? looks like multiplication to me.

no that was a division problem.. this (2x^4+8x^3+12x^3)

divided by 4x^3.

divided by 4x^3.
note that $\displaystyle 2x^4+8x^3+12x^3 = 2x^4 + 20x^3$

$\displaystyle \frac{2x^4 + 20x^3}{4x^3} = \frac{x}{2} + 5$

sure you copied it correctly?
