To solve ${x^2} - 15x + 56 = 0$ use the formula $\ x = \frac{{ - b \pm \sqrt {{b^2} - 4ac} }}{{2a}}$ where b = - 15,a = 1,c = 56. Is there a mathematical symbol I can use for "where" in this?

No! Maybe comma $","$ is the best symbolic way to write it out instead. – Apr 26 '17 at 16:38

Personally I think it reads better with 'where' left in rather than trying to compress the notation any more. – DMcMor Apr 26 '17 at 16:39

(let a in f a) and (f a where a is ...) are already mathematical constructs; there's no need for a symbol. They are equivalent to (\a. f a)(b) – Dmytro Apr 26 '17 at 17:52

I like the "where", but my Latex editor doesn't like me putting words and spaces into equations and it breaks the flow if I have to switch to plain text. – Michael McLaughlin Apr 27 '17 at 12:35

surely there's a workaround for making it usable; latex tends to be very clunky without the right modules – Dmytro May 01 '17 at 11:42
