This seems to a problem with your setup of preview latex. It
should work just fine.
For me the following org file works as expected -- also with
previewing the equation.
--8<---------------cut here---------------start------------->8---
#+LaTeX_header: \usepackage{amsmath} %% needed explicitely for org-preview-latex
* Test align
\begin{align}
(x+y)^3&=(x+y)(x+y)^2\\
&=(x+y)(x^2+2xy+y^2)\\
&=x^3+3x^2y+3xy^3+x^3.\qedhere
\end{align}
--8<---------------cut here---------------end--------------->8---
I do not seem to have any special setup for previewing latex,
though...
Sorry to be of no further help.
Regards,
Andreas
