Trouble Finding an Inverse LaPlace Transform

In summary, an Inverse LaPlace Transform is a mathematical operation used to find the original function from its LaPlace Transform. It is commonly used in engineering and physics to solve differential equations and understand the behavior of a function. There are several methods for finding an Inverse LaPlace Transform, including partial fraction decomposition, contour integration, and the use of properties and theorems. Some common challenges in finding an Inverse LaPlace Transform include dealing with complex functions and selecting the appropriate method. To verify the accuracy of a solution, one can check if it satisfies the original function and use tables of LaPlace Transform for comparison.

I am trying to find the inverse LaPlace transform of

[tex]F(s)=\frac{2s+12}{s^2+6s+2\sqrt{2}}[/tex]

Using partial fraction decomposition on the above rational expression seems tedious. Is there any other method?

Thanks
