bonjour quelqu'un peut m'aider MERCI ✨​

Bonjour,

3 (2x + 4) = 3 * 2x + 3 * 4 = 6x + 12

8 (3x + 2) = 8 * 3x + 8 * 2 = 24x + 16

(2 + x) * 6 = 2 * 6 + x * 6 = 12 + 6x = 6x + 12

3x (2x - 6) = 3x * 2x - 3x * 6 = 6x² - 18x

4 (4 + 6x) = 4 * 4 + 4 * 6x = 16 + 24x = 24x + 16

15 (2 - 3x) = 15 * 2 - 15 * 3x = 30 - 45x

(6x - 18) * x = 6x² - 18x

3 * (10 - 15 x) = 30 - 45x

(x² - 3x) * 6 = 6x² - 18x

(-9x + 6) * 5 = -45x + 30

(12x + 8) * 2 = 24x + 16

6x (-3 + x) = -18x + 6x² = 6x² - 18x
