\[ \int \frac {A+B x+C x^2+D x^3}{\sqrt {c+d x} (e+f x) \sqrt {a-b x^2}} \, dx=\int \frac {D x^{3}+C \,x^{2}+B x +A}{\sqrt {d x +c}\, \left (f x +e \right ) \sqrt {-b \,x^{2}+a}}d x \] Input:
int((D*x^3+C*x^2+B*x+A)/(d*x+c)^(1/2)/(f*x+e)/(-b*x^2+a)^(1/2),x)
Output:
int((D*x^3+C*x^2+B*x+A)/(d*x+c)^(1/2)/(f*x+e)/(-b*x^2+a)^(1/2),x)
