For #18 i might be way off. I used the proper techniques, but i don't know, i'll let y'all be the judge. My answer was [glow=green,2,300]-7/2 ln |x| + C[/glow]

 For 18, I got 2(sqrt x - 2) + 2 ln (x) + C  oh well probably wrong...what the heck.... I don't see any mistakes but when I take teh derivative, it's wrong.
