Chapter5, on Page 123,"The design of Cmos Radio Frequency Integrated Circuits", 1st Edition, T.H.Lee

How is the result (36) got from (35) ?
______________________________
/ ____________________
(35) α=√½[√(ω²LC)²+ω²(L²G²+R²C²) - ω²LC]
___ ___
(36) α≈½R√C/L +½G√L/C

I am so confused about it. My conclusion is like this:
____________
α≈½√CR²/L +LG²/C

Anybody can help calculate it ? Thanks a lot !
