Can any one with Mathematica help me with following integrals? O know those have closed -forms
\begin{equation} \int_{-\infty}^{\infty} \frac{x^4}{(a+bx^2)^2} e^{\frac{-x^2}{2c}} dx \end{equation}
\begin{equation} \int_{-\infty}^{\infty} \frac{x^3}{(a+bx^2)^2} e^{\frac{-x^2}{2c}} dx \end{equation}
a,b,c are real and positive.
