Problem in solving an Integral.I&#039;m solving a solid of revolution problem and I&#039;m stuck at this point. The u-subtitution doesn´t work, I don´t know what method use.  π  ∫  (            4      x      −      1              8              x        4                  )    2

This is the way that Andre suggest in the comment and the straightforward way:  (  4  x  −  1      )    2    =  16      x    2    −  8  x  +  1, then   (  4  x  −  1      )    2        /    (  64      x    8    )  =  1      /    4      x    6    −  1      /    8      x    7    +  1      /    64      x    8
