Help finding the slant asymptote.....

I'm so frustrated. The book I'm using for school doesn't show me how to do these, yet asks me to do them! I checked online for help and the same type of problems the book explains, is what everyone online to explaining. Please help.

The problem:

The answer:

I have no idea. The leading coefficient of the denominator is greater than that of the numerator. Can't find anywhere on how to do this! I am wasting so much time trying to figure this out. Please help.

Re: Help finding the slant asymptote.....

Do you know how to do polynomial division? What happens when you divide x^3 + 2x^2 + 4 by 2x^2 + 1?

Re: Help finding the slant asymptote.....

I do know how to do long division but the leading coefficient is larger than the leading coefficient of the numerator. You can't divide

by

. What do I need to multiply with

to get

? An x, but what about the 2? You can't divide 1 by 2. OH HELL. LOL. HA HA HA HA, that's funny. I just figured it out. LOL. Typing it all out in english is what cleared it up. WOW. I feel so stupid. HA HA HA.

I just have to say again that I feel so darn stupid. I don't know why I didn't see this before. I think I was stuck on everything being an integer.

God created the integers, all the rest was the work of men.
