Question

Factoriser chaque expression :
F = 5x + 35
G = 4x(x + 7)+ (x + 7)(3x −11)
H =(5x−1)(9x−4)+(7x+6)(5x−1) I=(3x+5)2 +(3x+5)(−2x+13. Merci de votre aide

  • Bonjour,

    F = 5 (x + 7)

    G = (x + 7) (4x + 3x - 11)

    = (x + 7) (7x - 11)

    H = (5x - 1) (9x - 4 + 7x + 6)

    = (5x - 1) (16x + 2)

    I = (3x + 5) (2 -2x + 13)

    = (3x + 5) (-2x + 15)

    Bonne journée
