Sagot :
Bonsoir,
A= 50x +40
B= 27x - 45x²
C= 12x +21 -8x +36 = 4x +57
D= 6x² +14x +15x +35 = 6x² +29x +35
E= 10x² -35x +16x -56 = 10x² -19x -56
F= 20x -16 -15x² +12x = -15x² +32x -16
G = 3x -2x² +21-14x + 20x² +5x -8x -2=
18x² -14x +19
H= 10x² -16x +15x -24 -( 8x² -6x -16x +12) =
10x² -16x +15x -24 - 8x² +6x +16x -12 =
2x² + 21x -36
Réponse:
bonjour,
A=5*18x
B=9x*2x
C=3*11x-4*(-7x)
D=7x*10x
E=13x*(-5x)
F=1x*1x
G=7x*1x+7x*9x
H=5x*(-3)-(-2)*1x
Bonne soirée
