Bonjour, j'ai besoin d'aide pour 2 exercices de maths.
Exercice 1: Résoudre les équations suivantes
a) (2x+2)+(4x-6)=0
b) x^2 -5x=0 (le "^" signifie la puissance ex: 2^3= 2 puissance 3)
Exercice 2: On donne A=(2x-3)(5-x)+(2x-3)^2
1) Développer et réduire A
2) Factoriser A
3) Résoudre l'équation (2x-3)(x+2)=0
Merci d'avance! :) ;)
