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
