factoriser 4x+4y= 2x+2y+2= 6x+3x= 25a+15b= 4a+8b-12c= 3x-3y-3 2x-4y-6z ​

Réponse :

4x+4y=4(x+y)

2x+2y+2= 2(x+y+1)

6x+3x= 3x(2+1) = 3x(3)

25a+15b= 5(5a+3b)

4a+8b-12c= 4(a+2b-3c)

3x-3y-3 = 3(x-y-1)

2x-4y-6z = 2(x-2y-3z)

Explications étape par étape :

Bonjour,

Factoriser:

4x+4y= 4(x+y)

2x+2y+2= 2(x+y+1)

6x+3y= 3(2x+y)

25a+15b= 5(5a+3b)

4a+8b-12c= 4(a+2b-3c)

3x-3y-3= 3(x-y-1)

2x-4y-6z= 2(x-2y-3z)
