Bonjour je pourrais avoir la correction de ​

Réponse :

bonjour

A = 8 x

C = 4 x

D = 6 x + 1

F = 3 b

G = 2 b + c + 1

A = - x - 3

B = - 21 x

C = 21 x

D = - 21 x²

E = 4 x

A = 2 x² + 2

B = x² - x

C = 2 x² - 4 x

D = - 8 x²

E = 10 u² + u - 6

A = x +21 - 3 x = - 2 x + 21

B = 6 +5 + x = x + 11

C = 30 x + 6 x²

D = 6 x + 5 + x = 7 x +5

E = 3 x + 5 + 4 x - 2 = 7 x + 3

F = 10 x +3 + 4 x -2 = 14 x + 1

G = - 9 x +1 + 4 - 5 x = - 14 x + 5

H = x - 7 - 4 x + 3 = - 3 x - 4
