Bonjour, J'ai besoin d'aide pour ces deux exercices:

Exercice 1: Résoudre les équations proposés
a. 7( 2x + 4 ) - 8x = 15x+1
b. 3( 2 - 4x ) = 4(x-1) + 2
c. ( 2x+3 )( x+1 ) = 4 - x(3-2x)
d. 4z^2 + 12z + 9 = (2z + 1 )^1

Exercice 2: PRODUIT NUL
a. ( 2 - 4x)( 3 + x) = 0
b. ( 5x + 1) ( 2x - 3 ) = 0
c. 3x( 2x + 1) = 0
d. ( x + 3 )( x - 2)( 2x + 1) = 0
