That page uses \frac{-b\pm \sqrt{b^2-4ac}}{2a} as the MathML "plain source" for
\frac{-b\pm \sqrt{b^2-4ac}}{2a}
Unfortunately, depending upon your browser's MathML renderer setting, reader-view may display it as:
−b±√b2−4ac2a
And, even when it doesn't look mangled, it always comes out as gibberish when reader-view passes it to text-to-speech. Although the exact details depend on what voice is chosen, what I'm hearing from reader-view right now is:
Exclamation mark minus exclamation mark b plus minus exclamation mark root exclamation mark b two exclamation mark minus exclamation mark four a c two a
Possible solution
Fortunately, this may be a solved problem. Here is a demo of how one can convert equations into speech:
The problem
Currently, using reader-view to listen to web pages that have mathematics in them is broken. For example, here is an article which discusses the quadratic equation: https://www.quantamagazine.org/the-symmetry-that-makes-solving-math-equations-easy-20230324

For example, pasting in
\frac{-b\pm \sqrt{b^2-4ac}}{2a}, gives us the following Clearspeak text that can be sent to TTS:Of course, that's a bit verbose, so it'd be nice if reader-view had an option to use Mathspeak instead which can be super-brief:
