Answer 4

Yep. There is a faster way. It's called Wolfram's Lighting Fast Answering Service.

Answer 5

yes, but I wanted to understand and I got it now... thanks

Answer 6

You must have overlooked the "show steps" button in wolfram alpha

Answer 7

I think partial fractions is the way to go. That's how they do it in wolfram, right?

Answer 8

Paul's online notes is a good website

Answer 9

i know how to do this

Answer 10

no fractions involved

Answer 11

Combination of splitting, substitution, complete the square, etc. That's how Wolfram Alpha does it.

Answer 12

yes, I love Paul's online notes. Spread the word! It's much more down to earth than Wolfram.

Answer 13

I don't think partial fractions would be of any help here! In my opinion, the key to solving this problem is the splitting part, which you probably have seen in Wollfarm Alpha solution.
