## Homework Statement

Evaluate the indefinite integral:

[tex]\int[/tex]7x+1/x^2+1 dx

## Homework Equations

## The Attempt at a Solution

My first attempt at the solution was to try using substitution. I set u=x^2+1. so du=2x dx and x=sqrt(u-1). Then I rewrote the integral so it is [tex]\int[/tex]7du/4usqrt(u-1). This is where I don't know where to go with this attempt.

I'm pretty sure I'm going about this problem all wrong. If I could just get a push in the right direction I'd really appreciate it :)
