\[ \int \frac {a g+e x-c g x^4}{\left (a+b x^2+c x^4\right )^{3/2}} \, dx \]
Optimal antiderivative \[ \frac {g x}{\sqrt {c \,x^{4}+b \,x^{2}+a}}-\frac {e \left (2 c \,x^{2}+b \right )}{\left (-4 a c +b^{2}\right ) \sqrt {c \,x^{4}+b \,x^{2}+a}} \]
command
Integrate[(a*g + e*x - c*g*x^4)/(a + b*x^2 + c*x^4)^(3/2),x]
