Salut ,
Factoriser les expressions suivantes
A = 3x + 3y
A=3(X+y)
B = – 8x + x²
B=-Xx(8-X)
C = 5 x (3x – 4) + 2(3x – 4)
C=(3X-4)x(5X+2)
D = 5(4x + 3) + 5x
D=5(4X+3+X)
D=5(5X+3)
E = (3x + 7) (4x +2) + (3x + 7) (x + 1)
E=(3X+7)x(4X+2+X+1)
E=(3X+7)x(5X+3)
F = 12x² – 4x
F=4Xx(3X-1)
G = (5x – 7)(8x – 3) + (–2x – 5)(5 x – 7)
G=(5X-7)x(6X-8)
G=(5X-7)x2(3X-4)
G=2(5X-7)x(3X-4)
H = (3x – 7)(5x – 3) – 4(3x – 7)
H=(3X-7)x(5X-3-4)
H=(3X-7)x(5X-7)
I = 2x² + 4x – 8
I=2(X²+2X-4)
J = (3x – 7)(5x – 3) – (2x – 5)(3x – 7)
J=(3X-7)x(5X-3-2X+5)
J=(3X-7)x(3X+2)
j'espère avoir pu t'aider !
