Salut,

5a - 5b = 5(a-b)

4x + x = x (4+1)

7x - xy = x(7-y)

-3a + 3ab = 3a ( -1 + b)

2z + z² - zx = z ( 2 + z - x)

J'espère t'avoir aidé !

bjr

5a - 5b =  5a -5 b=  5(a - b)

4x + x =  4x + 1x =  x(4 + 1) = 5x

7x - xy =  7x - xy =  x(7 - y)

-3a + 3ab =  -1*3a + 3ab =  3a(-1 + b)

2z + z² - zx = 2z + z*z - zx = 2z + z*z - zx = z(2 + z - x)
