How to solve cubic polynomials
WebA quadratic has only 2 roots, and only 2!=2 permutations. A cubic has 3 roots, so 3!=6 permutations. For the cubic, we manage to exploit some symmetries of the problem to reduce it to a quadratic equation. The quartic has 4 roots, and 4!=24 permutations, but we still manage to reduce it to a cubic equation by exploiting more symmetries. WebMar 3, 2024 · I'll assume that the coefficients of your cubic polynomials are integers, since that is true of your example. I see at least two ways to do what you want. First, you can use np.roots as you have been. Then round each solution to the nearest (real) integer and plug that integer into the original polynomial--this can be done with exact precision.
