To integrate ( \frac{2}{{x^3 - x^2}} ) using partial fractions, first factor the denominator, then decompose the fraction into partial fractions. In this case:
( \frac{2}{{x^3 - x^2}} = \frac{2}{{x^2(x - 1)}} )
We can rewrite this as:
( \frac{2}{{x^2(x - 1)}} = \frac{A}{x} + \frac{B}{x^2} + \frac{C}{x - 1} )
Multiplying both sides by the denominator ( x^2(x - 1) ), we get:
( 2 = A(x - 1) + B(x)(x - 1) + C(x^2) )
Now, we can solve for A, B, and C by comparing coefficients:
( 2 = Ax - A + Bx^2 - Bx + Cx^2 )
Equating coefficients of like terms, we get:
( 0x^2: B + C = 0 ) ( 1x: A - B = 0 ) ( 0x: -A = 2 )
Solving these equations simultaneously, we find:
( A = -2 ) ( B = -2 ) ( C = 2 )
Therefore, the partial fraction decomposition is:
( \frac{2}{{x^3 - x^2}} = \frac{-2}{x} + \frac{-2}{x^2} + \frac{2}{x - 1} )
Now, we can integrate each partial fraction separately:
( \int \frac{-2}{x} , dx = -2 \ln|x| + C_1 )
( \int \frac{-2}{x^2} , dx = 2 \frac{1}{x} + C_2 )
( \int \frac{2}{x - 1} , dx = 2 \ln|x - 1| + C_3 )
Finally, combining the results, we get:
( \int \frac{2}{{x^3 - x^2}} , dx = -2 \ln|x| + 2 \frac{1}{x} + 2 \ln|x - 1| + C )

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
