> For instance, a±b∓c means "a+b-c or a-b+c".
I feel like this would be less confusing if rendered as "±(a+b-c)". It's the same amount of cognitive effort for figuring out the second term/factor, but you get the first one for free.

The fact I made that mistake in the first place just makes me more convinced the original form is unnecessarily complex to parse.
(-b ± sqrt(b² - 4ac)) / 2a = 2c / (-b ∓ sqrt(b² - 4ac))
