Réponse :
bonjour,
A = 22 - 4x
A = 2(11-2x)
B = -4x +12
B = 4 (- x + 3 )
C = 10x + 6x - 2x² - 4x²
C = - 6x² + 16x
C = 2x ( -3x + 8)
D = - 4 - 2x + 2x² - 8 + 2x
D = 2x² - 12
D = 2 (x² - 6 )
E = 4x² - 12
E = 4 ( x² - 3 )
F = 4x - 12
F = 4 ( x -3 )
G = 10x - 3 +3 +6x
G = 16x
H = - 2x² - 6x + 6x + 12
H = - 2x² + 12
H = 2 ( - x² + 6 )
