Extract

The main object of the present note is to direct attention to the fact that Lill’s method for solving geometrically the general quadratic equation with real coefficients can be used effectively for the purpose of impressing upon students that even in elementary mathematics some very useful advances have been made recently. In 1867 E. Lui published an article in volume 65 of the Paris Comptes Rendus, from which the following method for solving the equation

x2 − ax + b = 0
