    No it is plum \[\int\limits_{}^{} \large \frac{6u^5} {u^2(u-1)}\] \[\large 6\int\limits_{}^{}\frac{u^3}{u-1} = \large 6\int\limits_{}^{}\frac{u^3-1^3}{u-1} +6\int\limits_{}^{}\frac{1}{u-1}\] Now continue :D

    You got to be kidding me @blockcolder just apply u^3-1^3 = (u-1)(u^2+1+u) and cancel the numerator u-1 and denominator u-1

    And then complete the square of the denominator and viola! A wild arctan appears!

    @blockcolder \[\large 6\int\limits\limits_{}^{}{(u^2+1+u)}du +6\int\limits\limits_{}^{}\frac{1}{u-1}\] \[\large 6u^3/3 + 6u+ 3u^2 + 6\log(u-1)\]
