Exploring the Expression (n^3 + 7n^2 + 14n + 3) / (n + 2)

This article dives into the expression (n^3 + 7n^2 + 14n + 3) / (n + 2), analyzing its simplification and potential interpretations.

Understanding the Expression

The expression represents a rational function, where a cubic polynomial (n^3 + 7n^2 + 14n + 3) is divided by a linear polynomial (n + 2).

Simplifying the Expression

We can simplify this expression using polynomial long division or synthetic division. Here's how we can simplify it using polynomial long division:

        n^2 + 5n + 4   
n + 2 | n^3 + 7n^2 + 14n + 3 
        -(n^3 + 2n^2)
        ----------------
              5n^2 + 14n
              -(5n^2 + 10n)
              ----------------
                       4n + 3
                       -(4n + 8)
                       ----------------
                            -5 

Therefore, the simplified form of the expression is:

(n^3 + 7n^2 + 14n + 3) / (n + 2) = n^2 + 5n + 4 - 5/(n + 2)

Interpretation and Applications
