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)
