1. ## Integration Problem =(

i need a lot of help intergrating...it's really hard...The way we're supposed to do it is by parts or trig substitution.

dx
([x^2]-4x)^(3/2)

any help would be awesome, thanks!

2. Is it meant to look like this $\int (x^2 - 4x)^{\frac{3}{2}}.dx$

3. ahh no soryr, the dx is supposed to be on top, either dx on top or a -(3/2) as the exponent

4. Put $x=\frac{4}{1-{{u}^{2}}},$ and show us where does that get you.

5. will that get me to parts or trig substitution?
