I need to evaluate the following integral with respect to x. If you guys can give me some hints on how to start off, it would be greatly appreciated.

[tex]f{x}[/tex](x) = [tex]\int\frac{\alpha\beta}{4}e^{(-\alpha|x| - \beta|y|)}dy[/tex]

The integral is evaluate from -infinity to infinity

From this I know that [tex]\frac{\alpha\beta}{4}[/tex] is a constant and can be taken out. I get confused on how to integrate the absolute value portion of it.

Thanks!
