I don’t know if it’s related to Western-centrism or not, but I recall thinking it was weird that my English-speaking colleagues do not know the formula to solve second-degree polynomials as the “Bhaskara formula”, as we call it in Brazil.

By the way, Wolfram’s website has an interesting summary of the history of this formula.[0]
