How to evaluate the integral below $$\int_{0}^{\infty }\frac{e^{-x^{2}}}{\sqrt{t^{2}+x}}\mathrm{d}x~~~~~~(t＞0)$$ The WolframAlpha gave me a horrible answer $$\frac{t}{2}e^{-\frac{t^{4}}{2}}\left \{ \pi \left [ \mathrm{I}_{-\frac{1}{4}}\left ( \frac{t^{4}}{2} \right )+\mathrm{I}_{\frac{1}{4}}\left ( \frac{t^{4}}{2} \right ) \right ]-4e^{\frac{t^{4}}{2}}\, _{2}F_{2}\left ( \frac{1}{2},1;\frac{3}{4},\frac{5}{4};-t^{4} \right ) \right \}$$ where $\mathrm{I}_{n}(z)$ is the modified Bessel function of the first kind and $_{2}F_{2}$ is the generalized hypergeometric function.
But I have no idea how to prove it.Is there a more simple solution for this integral.
Hint:
$\int_0^\infty\dfrac{e^{-x^2}}{\sqrt{t^2+x}}~dx$
$=2\int_0^\infty e^{-x^2}~d\left(\sqrt{t^2+x}\right)$
$=2\int_t^\infty e^{-(x^2-t^2)^2}~dx$
$=2\int_t^\infty e^{-x^4+2t^2x^2-t^4}~dx$
Similar to Evaluating $\int_{1}^{\infty}\exp(-(x(2n-x)/b)^2)\,\mathrm dx$
