What is the value of \(\frac{2013^3-2 \cdot 2013^2 \cdot 2014+3 \cdot 2013 \cdot 2014^2-2014^3+1}{2013 \cdot 2014}\)

What I have tried so far is I am using x to substitue 2013, and let 2014 becomes to (x+10), then after so many simplify step I get x^5+3x^2/x+1. I think my answer probably is wrong, can anyone give some idea about how to do this problem.
