## Homework Statement

Calculate the following:

[itex]\int^{-4}_{-6} (x^-1+5x)dx[/itex]

## Homework Equations

## The Attempt at a Solution

I've worked this down to

[itex]ln(-4) + 5(-4) - ln(-6) - 5(-6)

=ln(-4)-ln(-6)+10[/itex]

The answer to the left half (the ln parts) of the equation is undefined, and the right is 10..

So... undefined + 10? I'm unsure what to say the definite answer is....

Thank you for any help.
