bonsoir

Explications étape par étape :

C=5x(3x-4)+2(3x-4)

C=(3x-4)(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)(4x+2+x+1)

E=(3x+7)(5x+3)

F=12x²+4x

F=4x(3x+1)

G=(5x-7)(8x-3)+(-2x-5)(5x-7)

G=(5x-7)(8x-3-2x-5)

G=(5x-7)(6x-8)

H=(3x-7)(5x-3)-4(3x-7)

H=(3x-7)(5x-3-4)

H=(3x-7)(5x-7)

I=2x²+4x-8

I=2(x²+2x-4)

J=(3x-7)(5x-3)-(2x-5)(3x-7)

J=(3x-7)(5x-3-(2x-5))

J=(3x-7)(5x-3-2x+5)

J=(3x-7)(3x+2)

bonne soirée
