I am trying to help a friend with some what seems like basic calc stuff only it's been a while since I've done calc 1 and 2...

So I have several questions which I'll break down into three different new topics..

I am trying to evaluate the indefinite integral of 2X/X+3 dx

I put X+3 in the numerator like so (X+1)^ -1 but I'm not sure what to do from here... or if thats right.

Second question:

The definite integral evaluated from 7 to 10 of the absolute value of (X^2 - 81)/(X+9) dx

I realize that factors but would you do that? It would leave you with ((X+9)(X-9))/(X+9) which ultimate just leaves one factor of X-9 in the numerator.

So it would be the definite integral evaluated from 7 to 10 of absolute val (X-9)...

Any help would be greatly appreciated!
