Bonjour,
A: 4(3a +2b)
B: 3(x-3)
C: 5(x² -1)
D: x(6 -5x)
E: x²(x-2)
F: 5x(5x -3)
G: 7(x² -2x+7)
A:
(2x+3) ( -4x+1 + 8-x) =
(2x+3) ( -5x +9)
B:
(4-5x) ( 8x+2 -8+x)=
(4-5x ) ( 9x -6)
C:
(9x-4)(9x-4 +2x+1)=
(9x-4) ( 11x +3)
D:
(3x-2) ( -5x+8 -3x +2)=
(3x-2) ( -8x +10)
Réponse:
bonsoir voici la réponse que je propose j'espère qu'elle t'aide
EXERCICE 1 :
A=12a+8b
A=4×3a+4×2b
A=4(3a+2b)
B=3x-9
B=3×x-3×3
B=3(x-3)
C=5x²-5
C=5×x²-5×1
C=5(x²-1)
D=6x-5x²
D=6×x-5x×x
D=x(6-5x)
E=x³-2x²
E=x²×x-x²×2
