Quadratic Equation

Problem: Compute the values of x in the given quadratic equations ax^2+ bx + c for given a, b, c.


Solution in Python:

from __future__ import division

import math

def solve(a, b, c, eps=1e-12):

    if abs(a) < eps:
        return None, None

    discriminant = b * b - 4 * a * c
    if discriminant < 0:
        return None, None

    return (-b + math.sqrt(discriminant)) / (2*a), (-b - math.sqrt(discriminant)) / (2*a)
