SUMMARY

The integral ∫[dx]/[(1-x^2)√((x^2)-3x+2)] can be approached by completing the square within the square root and applying trigonometric substitution. Specifically, the substitution x - 3/2 = 1/2 sec(θ) is recommended for simplification. Users noted the importance of clarifying the integral's expression, as discrepancies exist between the title and the content of the post. Proper identification of the integral is crucial for effective problem-solving.

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.
