\int  \frac{2 {x}^{12} + 5 {x}^{9}  }{ {( {x}^{5}  +  {x}^{3} + 1)}^{3}  } dx
\int  \frac{2 {x}^{12} + 5 {x}^{9}  }{  {x}^{15} {( 1  +  {x}^{ - 2} +  {x}^{ - 5} )}^{3}  } dx
\int  \frac{2 {x}^{ - 3} + 5 {x}^{ - 6}  }{ {( 1  +  {x}^{ - 2} +  {x}^{ - 5} )}^{3}  } dx

Now put,

1  +  {x}^{ - 2} +  {x}^{ - 5}  = t
And solve.
