Stuck in integration: $\int {\frac{dx}{( 1+\sqrt {x})\sqrt{(x-{x}^2)}}}$ 
$\displaystyle\int {\frac{dx}{( 1+\sqrt {x})\sqrt{(x-{x}^2)}}}$
  $=\displaystyle\int\frac{(1-\sqrt x)}{(1+x)\sqrt{x-x^2}}\,dx$
$=\displaystyle\int\frac{(1-\sqrt x+x-x)}{(1+x)\sqrt{x-x^2}}\,dx$
  $=\displaystyle\int\frac{\,dx}{\sqrt{x-x^2}}-\displaystyle\int\frac{\sqrt x(1+\sqrt x)}{\sqrt x(1+x)\sqrt{1-x}}\,dx$

I have tried the above integration a lot . But not able to solve further . 
Please give me some hint how to proceed or some other method

By subtsitution twice we get $t=\sqrt { x } \Rightarrow dt=\frac { dx }{ 2\sqrt { x }  } $ $$\int { \frac { dx }{ \left( 1+\sqrt { x }  \right) \sqrt { x-{ x }^{ 2 } }  }  } =2\int { \frac { d\sqrt { x }  }{ \left( 1+\sqrt { x }  \right) \sqrt { 1-x }  } = } 2\int { \frac { dt }{ \left( 1+t \right) \sqrt { 1-{ t }^{ 2 } }  }  } \\ \\ $$
$t=\sin { z } \Rightarrow dt=\cos { z } dz$

$$\int { \frac { \cos { z } dz }{ \left( 1+\sin { z }  \right) \cos { z }  }  } =2\int { \frac { dz }{ 1+\sin { z }  }  } \overset { multiplying\quad both\quad (1-\sin { z) } \quad  }{ = } 2\int { \frac { 1-\sin { z }  }{ \cos ^{ 2 }{ z }  }  } dz=2\left( \int { \frac { dz }{ \cos ^{ 2 }{ z }  } -\int { \frac { \sin { z } dz }{ \cos ^{ 2 }{ z }  }  }  }  \right) =2\left( \tan { z } -\frac { 1 }{ \cos { z }  }  \right) +C=\\ =2\left( \tan { \left( \arcsin { \left( \sqrt { x }  \right)  }  \right) -\frac { 1 }{ \cos { \left( \arcsin { \left( \sqrt { x }  \right)  }  \right)  }  }  }  \right) +C=2\left( \frac { \sqrt { x }  }{ \sqrt { 1-x }  } -\frac { 1 }{ \sqrt { 1-x }  }  \right) +C=2\frac { \sqrt { x } -1 }{ \sqrt { 1-x }  } +C$$
