Historical Note on Quadratic Equation
The ancient Babylonians knew the technique of solving quadratic equations as long ago as $1600$ BCE.
The ancient Greeks, a thousand years or so later, solved quadratics by geometric constructions.
The general algebraic formulation of its solution did not appear until at least $100$ CE.
