Homework Statement
is there a general method of integrating this type of integral:
[tex] \int \sqrt{x -k} e^{-bx} [/tex]
Homework Equations
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
