Aidez moi svp Factorise les expressions A : 8x + 12y B : 49a - 56b C : 24x + 30y - 18z D : 15xy + 30xz E : 2xx + 8x F : 25xxy - 15xyy

A= 8x+12 y 
A= 4(3y+2x)

B= 49a-56b
B= -7(8b-7a)

C= 24x+30y-18z
C= -6(3z-5y-4x)

D=15xy+30xz
D=45xy

E= 2xx+8x
E= 2x(x+4)

F= 25xxy-15xyy
F= -5xy(3y-5x)

a = 8x+12y = 4(2x+3y)

b = 49a-56b = 7(7a-8b)

c = 24x+30y -18 = 6(4x+5y-3)

d = 15xy+ 30xz = 15x(y +2z)

e =2x²+8x = 2x(x+4)

f = 25x²y -15xy² = 5xy(x-3y)
