∫[tex] \frac{3 x^{2} - 5x}{x}dx[/tex]
It looks scary but always see if you can simplify before integrating. In this case you can just divide and get:
∫[tex]3x - 5[/tex]
Then you just use the power rule to get [tex] \frac{3 x^{2} }{2} - 5x[/tex]
If there's more to this problem then remember that we divided by x so x cannot be 0
