Can not paser inline math correctly

Resolved help
#1

Steps to reproduce

Type below: →

Can not parse the following line formula:

$ ax^2+bx+c=0 \left( 0 \right) $，$\Delta=b^2-4ac $
$\begin{align}
 x &= \frac{-b}{2a} + i \frac{\sqrt {4ac - b^2}}{2a} \\
 x &= \frac{-b}{2a} - i \frac{\sqrt {4ac - b^2}}{2a} \\
 i^2 &= -1
\end{align}$

Environment

#2

no spaces after/before $

#3

work with the first line formula if I edit to this:test$ax^2+bx+c=0 \left( 0 \right)$，$\Delta=b^2-4ac$test

But why I can’t put spaces before first $ and after last $? Also, where is the $ in the live edit model?

And still, the next multi-line formula is not rendered.
