Dear Sylvain,

I am using ’\startalign’

\starttext
\startformula
\startalign
\NC ax^2 + bx + c \NC = 0 \NR
\NC x \NC = = \frac{-b \pm \sqrt{b^2-4ac}}{2a} \NR
\stopalign
\stopformula
\stoptext

There is  a nice guide book "My Way” for math-alignment by Aditya.

Dear List,

The following example of equation alignment copied from An Excursion
is not reproducible under my context 2021.03.05 shipped with texlive
2021:

\starttext
\startformula
\eqalign{
ax^2+bx+c &= 0 \cr
x &= \frac{-b \pm \sqrt{b^2-4ac}}{2a} \cr
}
\stopformula
\stoptext

Both ampersands are rendered literally.

Does anyone know how to properly typeset aligned equations?


\starttext

\startformula
\startmathalignment%[align={right,left}]
\NC ax^2+bx+c \NC = 0    \NR
\NC x \NC = \frac{-b \pm \sqrt{b^2-4ac}}{2a} \NR
\stopmathalignment
\stopformula

\stoptext
