[itex]\int\frac{7x^2+4x+5}{x^3+x} dx[/itex]
I have to solve this using partial fractions and all I could think of was breaking it up into:
[itex]\frac{A}{x}+\frac{B}{x^2+1}[/itex]
also I tried
[itex]\frac{A}{x}+\frac{B}{x^2}+\frac{C}{x^3}+\frac{D}{x}[/itex] The reasoning behind this one was to split up original fraction into [itex]\frac{7x^2+4x+5}{(x^3+0)+x} dx[/itex]
Are either of these two even right? and if so I have no clue how to proceed.
Forgive me for not showing more work, but I have been staring at this for 30 minutes and can think of nothing. Thank you.
