Bonjour, vous pouvez m'aider svp ? ^^

factoriser:

k=7a²b -14 ab²

L= 25x² - 5x

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

F= (5x-6) (x-4)-(5x-6) (3-2x)

G= (3x-4) (1-2x)-(1-2x)

H-25-c²

merci

Bonsoir

Factoriser :

K = 7a²b-14ab²

K = 7ab(a-2b)

L = 25x²-5x

L = 5x(5x-1)

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

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

E = (5x+3)(1+3)

E = (5x+3)4

E = 4(5x+3)

F = (5x-6)(x-4)-(5x-6)(3-2x)

F = (5x-6)(x-4-(3-2x))

F = (5x-6)(x-4-3+2x)

F = (5x-6)(3x-4-3)

F = (5x-6)(3x-7)

G = (3x-4)(1-2x)-(1-2x)

G = (1-2x)(3x-4-1)

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

H = 25-c²

H = 5²-c²

H = (5-c)(5+c)

Bonne soirée.
