For this I'm using the sympy module. When I run the script, sympy returns the 4 solutions of the equation as complex numbers (see output), while, in fact, all of them are real. What is making sympy return the wrong answer? WebDec 17, 2014 · The Ferrari method is a method for reducing the solution of an equation of degree 4 over the complex numbers (or, more generally, over any field of characteristic $\ne 2,3$) to the solution of one cubic and two quadratic equations; it was discovered by L. Ferrari (published in 1545). crystal palace - arsenal prediction
