Explications étape par étape

Bonjour

Developper :

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

A(x) = 2x^2 + 6x + x + 3

A(x) = 2x^2 + 7x + 3

B(x) = (3x - 1)(2x + 5/3)

B(x) = 6x^2 + 5x - 2x - 5/3

B(x) = 6x^2 + 3x - 5/3

C(x) = (x + 7)^2

C(x) = x^2 + 14x + 49

D(x) = (3x + 11)^2

D(x) = 9x^2 + 66x + 121

E(x) = (4x - 8)^2

E(x) = 16x^2 - 64x + 64

F(x) = (5x - 13)(5x + 13)

F(x) = 25x^2 - 169

G = (V5 - 2V3)^2

G = 5 - 4V15 + 4 * 3

G = 17 - 4V15
