Was just looking at #Quadratic a couple of days ago as a potential spreadsheet solution. I liked that it integrated #Python into it. And then today I see that #Microsoft is planning on integrating Python into #Excel

a ² + b + c = 0 #Quadratic #RebrandedWithNoX

What I find interesting is: b^2 -4ac > 0 can be rewritten to say that the arithmetic mean of roots is > geometric mean. But what even IS geometric mean for two complex numbers?

This plane represents all possible #quadratic #equations with real coefficients.

The area in red is where both roots are real because the discriminant b^2 - 4ac is > 0. All the quadratics with imaginary roots lie inside the white region that's a parabola itself.

Interesting.
