Bonjour urgent svp :
FACTORISER
B= 4x+6 C= -9x²-9 D= 30x+36x² E= (x-2)(x+3)+(x-2)(x+6) F= (4x+5)²-5(4x+5)
G= (x+1)²-16

FACTORISER
B= 4x+6 C= -9x²-9 D= 30x+36x² E= (x-2)(x+3)+(x-2)(x+6) F= (4x+5)²-5(4x+5)
G= (x+1)²-16

FACTORISER
B= 4x+6
B = 2 (2x + 3)
C= -9x²-9
C = - 9 (x² + 1)
D= 30x+36x²
D = 6x (5 + 6x)
E= (x-2)(x+3)+(x-2)(x+6)
E = (x - 2) [(x + 3) + (x + 6)]
E = (x - 2) (x + 3 + x + 6)
E = (x - 2) (2x + 9)
F= (4x+5)²-5(4x+5)
F = (4x + 5) (4x + 5) - (20x + 5)
F = (4x + 5) [(4x + 5) - 20x - 5)
F = (4x + 5) (- 16x)
G= (x+1)²-16
G = (x + 1)² - 4²
G = [(x + 1 - 4) (x + 1 + 4)]
G = (x - 3) (x + 5)
