∫ ((xdx)/((x−1)(x−2)))=∫[(1/(x−2))+(1/((x−1)(x−2)))]dx  =ln∣x−2∣+∫[−(1/(x−1))+(1/(x−2))]dx  =ln∣x−2∣−ln∣x−1∣+ln∣x−1∣  =ln∣(((x−2)^2 )/(x−1))∣+cste  =>∫((xdx)/((x−1)(x−2)))=ln∣(((x−2)^2 )/(x−1))∣+cste   ..............le celebre cedric junior........

ln a −ln b =ln (a/b) ≠ ((ln a)/(ln b))  your answer is wrong

∫(x/((x−1)(x−2)))dx=∫((2/(x−2))−(1/(x−1)))dx=  =2ln ∣x−2∣ −ln ∣x−1∣ +C
