Bonjour , pouvez vous m'aider pour le 3e exercice svp ! mercii !​

Bonsoir

A = -3x ( 2 - x )

A = -6x + 3x²

B = 5x ( -7 - 2x)

B = - 35x - 10x²

C = -5 ( -7 - 2x)

C = 35 + 10x

D = -x ( -3x + 4)

D = 3x² - 4x

E = 8x + ( 7 - 6x)

E = 8x + 7 - 6x

E = 2x + 7

F = -8 ( 3x - 4)

F = - 24x + 32

G = 9x ( -2x + 3)

G = - 18x² + 27x

H = 2x - ( -4x + 7 )

H = 2x + 4x - 7

H = 6x - 7

E = 8 x + 7 - 6 x = 2 x + 7
