And another one:
√(6x - x^2 -8) dx
Thanks in advance
You may have a mistake in the first one -- see:
http://www.wolframalpha.com/input/?i=integral+x*sq...
and you will see it probably too complicated to do by hand in a reasonable length of time.
But for the second one, you can probably do it. Just go to this link and click "show steps"

1/
int by parts
---->(27/2)ln(√(x^2 +6x) +x+3)+(1/3)(x^2+6x)^(3/2)-(3/2)(x+3)√(x^2 +6x) + C
((-3 + x) x (6 + x) (9 + 2 x) +
162 Sqrt[x] Sqrt[6 + x] ArcSinh[Sqrt[x]/Sqrt[6]])/(6 Sqrt[x (6 + x)])
Merry Christmas.
