Question

Factoriser les expressions.
a. A = 3x + 6 R = 5x - 10
D = 12 + 18x E = 50 - 10x
G = 4x2 - 20x H = 3.x2 - 5x C = 4x + 9x F = x² + 7x I = 12x - 3
b. A = 7x + 7 B = 3x² + 3x
D = 10 - 20 x E = 4x² - 9x
C = 18x -9x
F = 10x² + 35x Pouvez-vous m’aider s’il vous plaît ! Je l’ai pour demain :)

    a. A = 3x + 6 = 3(x + 2)

    R = 5x - 10 = 5(x - 2)

    D = 12 + 18x = 6(2 + 3x)

    E = 50 - 10x = 10(5 - x)

    G = 4x² - 20x = 4x(x - 5)

    H = 3x² - 5x = x(3x - 5)

    C = 4x + 9x = 13x

    F = x² + 7x = x(x + 7)

    I = 12x - 3 = 3(4x - 1)

    b. A = 7x + 7 = 7(x + 1)

    B = 3x² + 3x = 3x(x + 1)

    D = 10 - 20x = 10(1 - 2x)

    E = 4x² - 9x = x(4x - 9)

    C = 18x - 9x = 9x

    F = 10x² + 35x = 5x(2x + 7)

    j'espère t'avoir aidé !
