F= 16x² - 2x
F= 2x * 8x - 2x * 1
F= 2x(8x - 1)

G= - 4(2x + 1) - (5x - 3)(2x + 1)
G= (2x + 1)(- 4 - (5x - 3))
G= (2x + 1)(- 4 - 5x + 3)
G= (2x + 1)(- 5x - 1)

H= 36x² + 12x + 1
H= (6x)² + 2 * 6x * 1 + 1²
H= (6x + 1)²

F(x)=16x²-2x=2x(8x-1)
g(x)=-4(2x+1)-(5x-3)(2x+1)=(2x+1)(-4-5x+3)=(2x+1)(-5x-1)
h(x)=36x²+12x+1=(6x+1)²     (produit remarquable)
