Bonjour j’ai besoin d'aide pour factoriser svp

A=2a+6
B=2ab+4b
C=x²-3x
D=2x³y²+4x²y⁴
E=6x²y³+4x⁴y⁴+2xy²
F=x(x+1)+2(x+1)
G=(x+5)(x-1)+(x+5)(2x+3)
H=(x²+3)(3x+5)-(x²+3)(x-6).

merci bcp

Bonjour

Factoriser :

A=2a+6

A = 2(a + 3)

B=2ab+4b

B = 2b (a + 2)

C=x²-3x

C = x (x - 3)

D=2x³y²+4x²y⁴

D = 2x²y² (x + 2y²)

E=6x²y³+4x⁴y⁴+2xy²

E = 2xy² (2x³y² + 3xy + 1)

F=x(x+1)+2(x+1)

F = (x + 1) (x + 2)

G=(x+5)(x-1)+(x+5)(2x+3)

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

G = (x + 5) (3x + 2)

H=(x²+3)(3x+5)-(x²+3)(x-6)

H = (x² + 3) (3x + 5 - x + 6)

H = (x² + 3) (2x + 11)

Réponse :

bonjour

A =  2 ( a + 3 )

B =  2b ( a + 2 )

C =  x ( x - 3 )

D =  2 x²y² ( x + 2 y²)

E=  2 xy² ( 3 xy+ 2x³y² + 1 )

F =  ( x + 1 ) ( x + 2 )

G = ( x + 5 ) ( x - 1 + 2 x + 3 ) = ( x + 5 ) ( 3x + 2 )

H ( x² + 3 ) ( 3 x + 5 - x + 6 ) = ( x² + 3 ) ( 2 x + 11 )
