factoriser les expressions suivantes
A= 6×2+6y = 6 x 2 + 6 x y = 6 (2+y)
B= 5×3-5×4 y = = 5 x (3-4y)
C = -2x² + 4 x = = x * (-2x) + x * 4 = x (-2x+4)
D = x² + 12 x = x * x + x * 12 = x (x+12)
E = x y + 4 x = x (y+4)
F = x² + x = x * x + x * 1 = x (x+1)
Réponse:
[tex]a = 6(2 + y) \\ b = 5(3 - 4y) \\ c = 2x( - x + 2) \\ d = x(x + 12) \\ e = x(y + 4) \\ f = x(x + 1)[/tex]
