Aider moi svp !! Je doit faire l’exercice 4!

Bonjour,

A = 4x² + 3x

A = x * 4x + x * 3

A = x(4x + 3)

B = 7x² - x

B = x * 7x - x * 1

B = x(7x - 1)

C = 2x + 5x³

C = x * 2 + x * 5x²

C = x(2 + 5x²)

D = 4x² + 8x

D = 4x * x + 4x * 2

D = 4x(x + 2)

E = 5x² - 15x

E = 5x * x - 5x * 3

E = 5x(x - 3)

F = 2x² + 8x⁴

F = 2x² * 1 + 2x² * 4x²

F = 2x²(1 + 4x²)

G = 5x³ - x² + 2x

G = x * 5x² - x * x + x * 2

G = x(5x² - x + 2)

H = - 4x³ - 4x² + 8x

H = - 4x * x² - 4x * x + 4x * 2

H = - 4x(x² + x - 2)

* = Multiplication

Bonne soirée.
