Bonsoir
Factorise les expressions suivantes.
E = (2x + 1)2 + (2x + 1)
E = (2x + 1)(2x + 1 + 1)
E = (2x + 1)(2x + 2)
E = (2x + 1) * 2(x + 1)
E = 2(2x + 1)(x + 1)
F = 3(2x - 3)2 – (2x - 3)
F = (2x - 3)(3(2x - 3) - 1)
F = (2x - 3)(6x - 9 - 1)
F = (2x - 3)(6x - 10)
F = (2x - 3) * 2(3x - 5)
F = 2(2x - 3)(3x - 5)
G = (x + 4)(3x + 4) – X – 4
G = (x + 4)(3x + 4) - (x + 4)
G = (x + 4)(3x + 4 - 1)
G = (x + 4)(3x + 3)
G = (x + 4) * 3(x + 1)
G = 3(x + 4)(x + 1)
H = (3x + 7)(2x + 1) + (x – 4)(- 2x - 1)
H = (2x + 1)(3x + 7 - x + 4)
H = (2x + 1)(2x + 11)
