Question

∫xsqrt(2x+1)dx

Answer 1

by parts might be simple enough

Answer 2

Nooooo were not in there yet

Answer 3

i dont readily see a nice u-sub ......

Answer 4

Let u= 2x+1?

Answer 5

du = 2dx? what happens to the x outside of the sqrt function

Answer 6

by u-subs
let u = 2x+1 ----> x = (u-1)/2

Answer 7

∫xsqrt(2x+1)dx
u = 2x+1
du = 2dx
\[∫x\sqrt{2x+1}dx\]\[=\frac{1}{2}\int(\frac{u-1}{2})\sqrt{u}du\]\[=\frac{1}{4}\int (u^\frac{3}{2}-\sqrt{u})du\]\[=...\]

Answer 8

....bleh!! like i said, simply hideous ;)
