Others have shown you ways of converting a lyx equation to latex.
However, if you prefer to keep your math in tex form all the time,
just use the ERT inset. Into it you can write any valid latex, including
latex math. And unlike the math inset, it will stay latex code forever.
Except in the output, where it obviously will be rendered.
Two ways to test the validity of such latex code:
1. view->pdf. Simple, but slow if you have a big document
2. Put the cursor first in the tex-box, hit delete to dissolve it.
The latex code becomes normal text. Mark it, and hit ctrl+M to
see if it turns out right. Afterwards, hit "undo" a few times
so you get your ERT inset back exactly as it was.
You don't need to use the LyX math editor if you don't want to,
even if you write math in LyX.
