Answer
$\displaystyle \frac{x+1}{x+2}$
(sample answer)
Work Step by Step
In order to simplify, we have to
1. Factor the numerator and the denominator completely.
2. Divide both the numerator and the denominator by any common factors.
So, we find two polynomials that have no common factors,
say, $(x+1)$ and $(x+2).$
$\displaystyle \frac{x+1}{x+2}$
