Bonjour,
E = 5x – 4 + 9x - 8x + 1 - 7
= 6x - 10
F = 8 – 6x + 2 – x – 3 + 9
= -7x +16
G= - 3x + x² + 6x
= x² +3x
H = 13x - x + 7
= 12x +7
Bonjour,
Réduire chaque expression :
E = 5x - 4 + 9x - 8x + 1 - 7
E = 5x + 9x - 8x - 4 + 1 - 7
E = 6x - 10
F = 8 - 6x + 2 - x - 3 + 9
F = -6x - x + 8 + 2 - 3 + 9
F = -7x + 16
G = -3x + x² + 6x
G = x² - 3x + 6x
G = x² + 3x
H = 13x - x + 7
H = 12x + 7
✅
Bonne journée.
