Definitely better as the original. Works here as expected.
Still one element making problems:
	Warning: Failed to produce 1 preview snippet(s)
Looking at the lyxpreviewkn4998.log here, looks like it is not related to your patch.

Preview: Snippet 85 338603 0 465893
! Undefined control sequence.
l.628 x^{2}-2x-2\Rightarrow\question
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

Other snippets are OK.
