I'm not sure where parentheses belong.
If the problem is: (3x - 2)/(x - 1) = x/(x + 1) - (3 - 2x)/(1 - x2)
---> (3x - 2)/(x - 1) = x/(x + 1) - (3 - 2x)/[(1 - x)(1 + x)]
Multiply all the terms by (1 - x)(1 + x) and simplify:
---> - (3x - 2)(1 + x) = x(1 - x) - (3 - 2x)
---> -(3x2 + x - 2) = x - x2 - 3 + 2x
---> -3x2 - x + 2 = -x2 + 3x - 3
---> -2x2 - 4x + 5 = 0
---> 2x2 + 4x - 5 = 0
Using the quadratic formula: x = (-4 ± √[42 - 4(2)(-5)] / [2(2)] ---> x = ( -2 ± √14 ) / 2
I skipped many steps; any questions?
Also, I might have guessed the wrong problem ...
