Ce script résout les équations du second degré : Pour cela, entrer “roots(a,b,c)” et remplacer a, b et c par vos valeurs. Le script affichera entre accolades la valeur de delta et plus loin les solutions.

from math import *
def roots(a,b,c):
  delta = b*b-4*a*c
  if delta == 0:
    return {delta}, -b/(2*a)
  elif delta > 0:
    x_1 = (-b-sqrt(delta))/(2*a)
    x_2 = (-b+sqrt(delta))/(2*a)
    return {delta}, x_1, x_2
  else: return {delta}
