Trying to help someone simplify this: (2ab - 3b^2)/(3b - 4a)

[e^(i Pi)+1=0]

I managed to get it down to 2ab/(4a-3b)-b, but that doesn't seem very simplified to me. I also added and subtracted terms in the numerator to make it factorable, ect but nothings really worked out.

There are no factors that are common to both the numerator and denominator, so I don't see that $\frac{2ab - 3b^2}{3b^2 - 4a}$ can be simplified at all.

Thanks. I wasn't sure if I was missing something.
