Sagot :
Bonjour
x+4----> 1/3 + 4 = 1/3 + 12/3 = 13/3
x(x-4)----> 1/3 (1/3 - 4) = 1/9 - 4/3 = 1/9 - 12/9 = - 11/9
x+4 = 1/3 + 4 = 1/3 + 12/3 = 13/3.
salut c'est simple il faut faire
x+4----> 1/3 + 4 = 1/3 + 12/3 = 13/3
x(x-4)----> 1/3 (1/3 - 4) = 1/9 - 4/3 = 1/9 - 12/9 = - 11/9
x+4 = 1/3 + 4 = 1/3 + 12/3 = 13/3.
