$$\int{\frac{5x^3+8x^2+x+2}{x^2(2x^2+1)}} dx$$
So ... how do I start? Numerator cant be factorized it seems, and this looks like a complicated expression ...
I tried expanding the denominator to see if integration by substitution will work, but it didn't give any ideas
$$\int{\frac{5x^3+8x^2+x+2}{2x^4+x^2}} dx$$
I don't see a clear way to integrate by parts either. Can anyone enlighten me?
