Hi, I'm trying to work out the variance of the gamma(I'm up the the part where you multiply [tex] x^2[/tex] by the function), but i don't know how to work out what(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\gamma(\alpha + 2) [/tex] equals to

i know im supposed to use the fact that [tex] \gamma(\alpha + 1) = \alpha \gamma(\alpha) [/tex]

but i dont understand what to do, please help
