Bonjour,
A = 3(7x - 2)
= 3*7x - 3*2
= 21x - 6
B = -4x(2x - 9)
= -4x * 2x - (-4x)*9
= -8x² - (-36x)
= -8² + 36x
C = 6x + 2(-7x - 5)
= 6x + 2 * (-7x) - 2 * 5
= 6x + (-14x) - 10
= 6x - 14x - 10
= -8x - 10
D = 3x - 5(2x + 4)
D = 3x - 5 * 2x - 5 * 4
D = 3x - 10x
- 20
D = -7x
- 20
En dessus la correction, j'ai refais pour vérifier si tu as bon et.. C'est tout juste, bravo ! ^^ Mais juste pour le D c'est - 20 pas + 20
