Procedural Documentation for Rational Expression Simplification

In the process of streamlining a logistics cost formula, an analyst encounters the expression:

3n9n2+n6n+32n\frac{-3n-9}{n^2+n-6} - \frac{n+3}{2-n}

To find a common denominator, the analyst first factors the trinomial into (n2)(n+3)(n - 2)(n + 3). In your own words, describe the specific algebraic relationship between the denominator (2n)(2 - n) and the factor (n2)(n - 2). Detail the standard procedure for rewriting the second fraction so that it uses (n2)(n - 2) as its denominator, and explain how this transformation specifically changes the subtraction operation between the two fractions.
