Bonsoir
Factoriser :
F(x) = x^2 - x
F(x) = x * x - x * 1
F(x) = x(x - 1)
G(x) = (x + 1)(x + 5) - x(x + 1)
G(x) = (x + 1)(x + 5 - x)
G(x) = (x + 1)(5)
G(x) = 5(x + 1)
H(x) = (x^2 - 1) - (3x + 4)(x - 1)
H(x) = (x - 1)(x + 1) - (3x + 4)(x - 1)
H(x) = (x - 1)(x + 1 - 3x - 4)
H(x) = (x - 1)(4x - 3)
I(x) = (x + 1)^2 - (5x + 1)^2
I(x) = (x + 1 - 5x - 1)(x + 1 + 5x + 1)
I(x) = (-4x)(6x + 2)
I(x) = (-4x) * 2(3x + 1)
I(x) = (-8x)(3x + 1)
J(x) = (1 - x)(3x - 8) - 2(x - 1)(3x + 2)
J(x) = (1 - x)(3x - 8) + 2(1 - x)(3x + 2)
J(x) = (1 - x)(3x - 8 + 2(3x + 2))
J(x) = (1 - x)(3x - 8 + 6x + 4)
J(x) = (1 - x)(9x - 4)
