You example shows that the author does not know how to deal with the
issue. While not every math expression has a text equivalent, many
have. In your particular example  the only problem are ^2, so alt text


So your alt text is

ax\texttwosuperior + bx + c



See hyperref manual p. 18 (sect 4.1.2)

You need to call hyperref

PS Not sure if you want a=1 or a\ne 1; the latter is more difficult

Some symbols which are not declared there (\ne) one can still declare
in preamble: f.e. I use


which I found by analyzing unicode (UTF8) table. Not sure why they are
not declared

PPS General tex questions are better addressed in texhax list as some
ver knowledgeable people don't use Mac and don't subscribe this list
