1 * a = a
1st: toute valeur de x rend I'<span>équation vraie
tous les nombres r</span><span>éels
2nd: r</span><span>ésoudre l'équation pour x en trouvant a, b et c du quadratique puis en appliquant la formule quadratique
x = 2 ± i</span>
I think it was be 220 because if theres 55 in a 10 stack it should be 55x4
