(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

is there a general method of integrating this type of integral:

[tex] \int \sqrt{x -k} e^{-bx} [/tex]

2. Relevant equations

3. The attempt at a solution

[tex]x-k={u}^{2}[/tex]

[tex]dx=2udu[/tex]

[tex] \int u^2 \,{e}^{{-b\left( {u}^{2}-k\right) }}du [/tex]

[tex] \int {u}^{2}\,{e}^{{-b\,{u}^{2}}+{b\,k}}du [/tex]

and it seems worse than its starting point
