bonjour

A = 3 x + 4 - 5 x - 2 = - 2 x + 2

B = 5 x - 2 x + 3 = 3 x + 3

C = - 4 x² - 2 x² + 3 x - 1 - 2 x + 3 = - 6 x² + x + 2

D = - 3 x + 5 - 7 x + 2 x - 6 x - 6 = - 14 x - 1

Bonjour,
A=3x+4-5x-2=-2x+2
B=5x-2x+3=3x+3
C=-4×-2×+3×-1-2×+3=-6×+×+2
D=-3x+5-7x+2x- 6x - 6 = - 14 x - 1
bon courage à toi !! :)
