A small library for solving quadratic (and linear) equations, including complex roots.

mathemagics

A tiny library for solving quadratic (and linear) equations of the form ax^2 + bx + c = 0, including complex roots.

Install

pip install mathemagics

Usage

from mathemagics import solve_quadratic

x1, x2 = solve_quadratic(1, -3, 2)
print(x1, x2)  # 2.0 1.0

Return value

solve_quadratic(a, b, c) returns a tuple (x1, x2):

• If a == 0 and b == 0: no solution exists; returns (nan, nan).
• If a == 0 and b != 0: the equation is linear; x1 and x2 are equal.
• If a != 0 and the discriminant is non-negative: x1 and x2 are real numbers.
• If a != 0 and the discriminant is negative: x1 and x2 are complex roots, each represented as a (real_part, imaginary_part) tuple.
