Bonjour, comment fait on avec la forme canonique pour savoir si il y a deux racine, une racine, ou bien zéro racine.
Exemple avec 2x² - 4x + 5 = 0 Δ = -24 Donc aucune racine
Mais a partir de ça :
2x² - 4x + 5 = 0
2(x²-2x) + 5 = 0
2[(x-1²)-1] + 5 = 0
2(x-1)² + 3 = 0
2(x-1²) + 3/2 =0
Comment à partir de ça peut'on dire que il n'y a aucune solution SVP.
Merci pour vos réponses
