export bug when inserting systems of quadratic equations

I am a high school math teacher. One feature I particularly like about Keynote is its support for LaTeX language for inserting formulas. I often export Keynote presentations as PowerPoint files to use in the classroom. However, when inserting systems of quadratic equations, there is a compatibility issue with the PowerPoint export that causes the export to fail. I am seeking a solution to this problem. Thank you.For example，“\begin{cases}x=t(y+2) \\ x^{2}+2 y^{2}=4\end{cases}”can be used in keynote,but can not be exported properly to ppt

Use a bracket + array structure, use aligned, rasterize the formula before export, or insert equations after export in PPT.

The safest LaTeX fix is:


\left\{
\begin{array}{l}
x = t(y+2) \\
x^{2} + 2y^{2} = 4
\end{array}
\right.

You already have another thread about the same issue.

It has not really anything to do with quadratic equations per se, if you use LaTeX formulas in

Keynote they don't transfer to Powerpoint.

This is just not supported in Powerpoint the same way it is in Keynote.

Unless Powerpoint starts supporting it, which of course only Microsoft can do, you will need to

use other options, as pointed out in the other thread: either use Keynote to present, if possible (that would be best, of course), or export to pdf, or rasterize.

Did you actually test this in either Keynote v14.4 or PowerPoint v16.103.3? It does not work in either.

Among the guidelines for the support communities is that one should test code or examples before posting, and confirm that accuracy with the applications in question. This is what I and Luis do.
