Help with integration using tables
I'm having trouble with this problem. I'm supposed to use a table of integrals to integrate this, so I'm supposed to tweak it so it looks like one of the equations on the table, but I'm not having much success.

Integral of dx/(2x^3-3x^2)

I've tried factoring out the x^2 and then using partial fraction decomposition, but that didn't work. Also, I tried u-substitution after factoring out the x^2 with u = x^2 but I don't think that worked either. Is factoring out the x^2 the right step?

Please help? Thanks.

Put $x=\frac1u$ and you'll end up with an integral so that you can apply partial fraction descomposition.

Hi,

What do you mean when you say put u = 1/x? That is u substitution right? I tried that but I'm not sure how that's supposed to help...You may very well be right but I'm a bit rusty with my math.
