One of my many obligations

is main­tain­ing a blog for Larry’s stu­dents. Since he teaches math, that means mak­ing sure that the math plu­gin works. I dug through the php code for the plu­gin, pretty much doing noth­ing but trans­lat­ing from French to English (thank you, iTrans­late!) and tidy­ing up the code. And now some­thing that sup­pos­edly didn’t work does. Yay! Not a clue why, but still yay.

So here’s the qua­dratic for­mula, as ren­dered by my mod­i­fied ver­sion of wpmath­plu­gin.

The text, to be enclosed in math tags.
x = {-b pm sqrt{b^2 — 4ac}}/{2a}

The result:

Cool, eh?
