salut es que vous pouvez m'aider pour l'exo svp. merci ​

Bonjour

a.

A = 3x + 6 = 3 (x + 2)

D = 12 + 18x = 6 (2 + 3x)

G = 4x² - 20x = 4x (x - 5)

R = 5x - 10 = 5 (x - 2)

E = 50 - 10x = 10 (5 - x)

H = 3x² - 5x = x (3x - 5)

C = 4x + 9x = x (4 + 9) = x (13).

F = x² + 7x = x (x + 7)

I = 12x² - 3 = 3 (4x² - 1) = 3 (2x - 1) (2x + 1)

b.

A = 7x + 7 = 7 (x + 1)

B = 3x² + 3x = 3x (x + 1)

C = 18x - 9x = 9x (2 - 1)

D = 10 - 20x = 10 (1 - 2x)

E = 4x² - 9x = x (4x - 9)

F = 10x² + 35x = 5x (2x + 7).
