Aidez-moi pour l’exercice 3 svp pour sauf la a , e, c. Merci^^

Bonjour,

b. 5a - 5b + 5c = 5(a - b + c)

d. 24a - 16b = 8(3a - 2b)

f. 6x - 6 = 6(x - 1)

g. 12x - 4y = 4(3x - y)

h. 6x² - 12x = 6x(x - 2)

Bonjour,

5a - 5b + 5c = 5 * a - 5 * b + 5 * c = 5(a - b + c)

24a - 16b = 8 * 3 * a - 4 * 4 * b = 8(3a - 2b)

6x - 6 = 6 * x - 6 = 6(x - 1)

12x - 4y = 3 * 4 * x - 4 * y = 4(3x - y)

6x² - 12x = 6x * x - 6x * 2 = 6x(x - 2)
