Forcing Math via Entities

Can you recognize this as the quadratic formula in your browser?
If ax² + bx + c = 0
then x = (-b ± (b² - 4ac)^½) / 2a

The HTML code for inserting an entity has the following components:

- an ampersand
- either
- a hash mark followed by the character number, or
- the character name (much less support for this)

- a semicolon

Examples:
- © is generated by &#nnn; for nnn=169
- & is generated by &xxx; for xxx=amp
