Bonjour je nul en math pouvez vous m'aidez je ni comprend rien merci d'avance
1: A = 5+(2x+3)
B= 5x-(3-4x
C= (x-4) - 6
D= (4x + 2 ) + ( -6x -2 )
E= - (-3x - 1 ) + (x-3)
F = 8x - (5x +2) + (3-4x)
2): Replace dans chacune des expressions tous les signes x sous entendus
E=3x² + 5x -10
F= 4y(21-3y)
G (2z -1) (5-z)

Bonjour,A = 5 + 2x + 3
A = 2x + 8
A = 2(x + 4)
B = 5x - 3 + 4x
B = 9x - 3
B = 3(3x - 1)
C = x - 4 - 6
C = x - 10
D = 4x + 2 - 6x - 2
D = -2x
E = 3x + 1 + x - 3
E = 4x - 2
E = 2(2x - 1)
F = 8x - 5x - 2 + 3 - 4x
F = -x + 1
2)
E = 3 * x * x + 5 * x - 10
F = 4 * y * (21 - 3 * y)
G = (2z - 1) * (5 - z)
