Divide. show your work. (n^5-18n^4+3n^3)/n^3

Remark
Nicely shown with the brackets so we know exactly what the question is. 
You must remember that the division takes place on all 3 terms. You can't leave anything out. You must also remember that since nothing will combine now, nothing will combine in your answer.


= n^2 - 18n + 3

Method Two.
I almost hesitate showing you this because you may not have taken it yet, but keep in mind that you can take you a common factor like this.

n^3(n^2 - 18n + 3)/ n^3  The n^3 cancel.
n^2 - 18n + 3
