 So we'll do this by integration by parts. So we'll pick a part to be u and a part to be dv. Well, how about u equals x and dv is log of x plus 3 dx? Now, we do have to find the derivative and the anti-derivative, and while it's easy to differentiate x, it's much harder to anti-differentiate log of x plus 3, so we don't want to do this. So instead, we'll make u log of x plus 3 and dv x dx. And we can differentiate log and anti-differentiate x dx. And so that'll be uv minus the integral of v du. We'll clean up the algebra a little bit. Now we have the integral of a rational expression, so let's go ahead and use partial fractions on that. So remember, the first thing we'll need to do is write this in the form of a proper rational expression, which means dividing x squared by x plus 3, and that gives us... And now we can integrate, and since this is an indefinite integral, plus c.
