I need some help deriving the quality factor in an rcl circuit(adsbygoogle = window.adsbygoogle || []).push({});

Q=Lw(sub 0)/R. So far I know that Q=w(sub 0)/delta but my professor used this formula to continue the derivation delta w=R/L and I don't know where it comes from. Can anyone give me a hint?
