# Weird Integral Problem

## Homework Statement

$$\int (x+8)/(x+4)$$

N/a

## The Attempt at a Solution

I tried to split the problem which resulted in:

$$\int x/(x+4) + \int 8/(x+4)$$

But now I'm stuck,and this is a bonus question on my AP Calculus homework.

Do polynomial division and it becomes much simpler.

It might help to factor it like this:

$$\frac{x+8}{x+4} = \frac{(x+4)+4}{x+4}$$

Then use the same trick you did.

That's pretty slick.

Thanks, it's my own little algebraic trick.

Thanks for the help!

It is, of course, the same as the "polynomial division" that gb7nash suggested.

Srsly? The way I learned polynomial division is much, much harder.

I think "much much harder" is a srs exaggeration.

Well I mean, I learned it the way long division is taught, and I never liked long division. I prefer my method, whether it's called polynomial division or not.
