How can I integrate this? I already tried substitution u=x-1 and partial fractions.

∫[dx]/[(1-X^2)√((x^2)-3x+2)]

2. Relevant equations

How I'd start would be to first complete the square inside the square root, then do a trigonometric substitution of $\displaystyle x - \frac{3}{2} = \frac{1}{2} \sec x$. Try it out and see what you get.
