Mupad [F(-1)]

Timed out. \[ \int \frac {\sqrt {1-2 x^2} \sqrt {3+5 x^2}}{\sqrt {7-11 x^2}} \, dx=\int \frac {\sqrt {1-2\,x^2}\,\sqrt {5\,x^2+3}}{\sqrt {7-11\,x^2}} \,d x \] Input:

int(((1 - 2*x^2)^(1/2)*(5*x^2 + 3)^(1/2))/(7 - 11*x^2)^(1/2),x)
 

Output:

Reduce [F]

\[ \int \frac {\sqrt {1-2 x^2} \sqrt {3+5 x^2}}{\sqrt {7-11 x^2}} \, dx=-\left (\int \frac {\sqrt {5 x^{2}+3}\, \sqrt {-2 x^{2}+1}\, \sqrt {-11 x^{2}+7}}{11 x^{2}-7}d x \right ) \] Input:

int((-2*x^2+1)^(1/2)*(5*x^2+3)^(1/2)/(-11*x^2+7)^(1/2),x)
 

Output:

 - int((sqrt(5*x**2 + 3)*sqrt( - 2*x**2 + 1)*sqrt( - 11*x**2 + 7))/(11*x** 
2 - 7),x)
