Bonjour
besoin d’aider pour factoriser les expressions suivantes
A = 3x + 3y
B = – 8x + x²
C = 5 x (3x – 4) + 2(3x – 4)
D = 5(4x + 3) + 5x
E = (3x + 7) (4x +2) + (3x + 7) (x + 1)

F = 12x² – 4x

G = (5x – 7)(8x – 3) + (–2x – 5)(5 x – 7)
H = (3x – 7)(5x – 3) – 4(3x – 7)

I = 2x² + 4x – 8
J = (3x – 7)(5x – 3) – (2x – 5)(3x – 7)
Merci par avance

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 !
