I have maple and have used other tools online to find the answer, but I don't know the steps taken to get to it, I have a feeling its some algebra tricks that I'm just not remembering, but onto the problem.
Its the integral of X/(sqrt(5+X)) from a=-1 to b=4, The indefinate integral is
2 (-10 + x) Sqrt[5 + x]
-----------------------

I just don't know how it got to that point, Please help!

I've tryed substituting u=5+x and even u=sqrt(5+x) I just can't seem to get anywhere with it, I think I'm doing soemthing wrong with converting the top x to u, Please Help meeeeeeee
bumping is against the rules, and you have gotten help
if you follow post #2's suggestion (yes, you must change the x to u - 5) then you end up with
if you follow post #3's suggestion, then you end up with
either is fine, it is up to you to do which you prefer. is there anything you do not understand on how we got these new integrals?
