bonsoir
A = 12 x + 60
B = 15 x + 15
C = 2 x + 16
D = 24 x - 54
E = - 18 x + 12
Bonsoir ! J'espère vous aider !
Réponse :
A = 12*(x + 5)
A = 12*x + 12*5
A = 12x + 60
B = 5*(3x + 3)
B = 5*3x + 5*3
B = 15x + 15
C = 2*(x + 8)
C = 2*x + 2*8
C = 2x + 16
D = 6*(4x - 9)
D = 6*4x - 6*9
D = 24x - 54
E = -3*(6x - 4)
E = -3*6x + 3*4
E = -18x + 12
