I read the article. It is called "pq formeln" _in Swedish_. The p and q refers to the traditional names of the coefficients.
I cannot find any link in English referring to it, but it is part of the standard curriculum.
One example of a website explaining it here below (in Swedish), but still, you can clearly see that it's the same formula OP has given:

- jonsen 5y agoRight, but this just describes how to use this variant of the more standard formula. What is interesting is how do you derive the formula.
- sedeki 5y agoYup, agreed. But this the standard formula everyone here memorizes, so I thought it might be interesting since it wasn't mentioned anywhere in the article. I did refer to the "result" rather than the derivation.
