Start by dividing the two polynomials. The resultant expression will be much simpler.

Instead of trying to factor simply divide it into 3 different equations i.e.


\int \frac{x^{2}}{x+1}dx - \int \frac{3x}{x+1}dx + \int \frac{2}{x+1}dx

\int \frac{x^{2}}{x+1}dx - \int \frac{3x}{x+1}dx + \int \frac{2}{x+1}dx

These aren't equations: they are expressions.

A much simpler approach is to do as jgens advised, and divide x^2 - 3x + 2 by x + 1, using long division.
