1. Réponse maudmarine
54-18y = 18 (3 - y)
-49+21y = 7 (- 7 + 3y)
36y + 63 = 9 (4y + 7)
5y+25 = 5 (y + 5)
3y*y+y = y (3y + 1)
8y*y+2y = 2y (4y + y)
-y+3y*y = y (- 1 + 3y)
3y*y+9y*y = 3y (y+ 3y) -
2. Réponse peg05
54-18y = -18(y-3)
-49+21y= 7(3y-7)
36y+63= 9(4y+7)
5y+25= 5(y+5)
3yxy+y= y(3y+1)
8yxy+2y= 2y(4y+1)
-y+3y*y= y(3y-1)
3yxy+9yxy= 12y²
