Homework Statement



e∫^P(x)

∫\frac{x-2}{x(x-1)}dx

The Attempt at a Solution



so i split it into

∫\frac{x-2}{x(x-1)}dx
= ∫\frac{2x-1}{x^2-x}dx - ∫\frac{x+1}{x^2-x}dx

= ln(x2-x) - ∫\frac{x}{x^2-x} - ∫(x2-x)-1

= ln(x2-x) - ln(x-1) - ∫(x2-x)-1

ok. having problems working out ∫(x2-x)-1dx
tried many ways but i keep ending up with the original integral.

u=x-1 --> du=-x-2
dv= (x-1)-1dx --> v=ln(x-1)

gives me (\frac{1}{x})ln(x-1) + ∫\frac{ln(x-1)}{x^2}dx

when i work this out

∫\frac{ln(x-1)}{x^2}dx

u=ln(x-1) --> du=\frac{1}{x-1}
dv=x-2dx --> v=-x-1

i get

∫\frac{ln(x-1)}{x^2}dx = \frac{-ln(x-1)}{x} + ∫(x2-x)-1

which is the same integral and above and i get no solution.

Use partial fraction decomposition on \displaystyle\frac{x-2}{x(x-1)}\,.
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
