(D) આપેલ આંશિક અપૂર્ણાંક વિઘટન: $\frac{x-2}{x^2(2x-3)} = \frac{A}{x} + \frac{B}{x^2} + \frac{C}{2x-3}$.બંને બાજુ $x^2(2x-3)$ વડે ગુણતા: $x-2 = Ax(2x-3) + B(2x-3) + Cx^2$.$x = 0$ લેતા: $-2 = B(-3) \Rightarrow B = \frac{2}{3}$.$x = \frac{3}{2}$ લેતા: $\frac{3}{2} - 2 = C(\frac{3}{2})^2$ $\Rightarrow -\frac{1}{2} = C(\frac{9}{4})$ $\Rightarrow C = -\frac{2}{9}$.$x^2$ ના સહગુણકોની સરખામણી કરતા: $0 = 2A + C$ $\Rightarrow 2A = -C = \frac{2}{9}$ $\Rightarrow A = \frac{1}{9}$.હવે, $2(A-C) = 2(\frac{1}{9} - (-\frac{2}{9})) = 2(\frac{1+2}{9}) = 2(\frac{3}{9}) = 2(\frac{1}{3}) = \frac{2}{3}$.કારણ કે $B = \frac{2}{3}$, તેથી $2(A-C) = B$.

જો $\frac{x-2}{x^2(2x-3)} = \frac{A}{x} + \frac{B}{x^2} + \frac{C}{2x-3}$ હોય, તો $2(A-C) = $
