bonjour

Identifier le facteur commun et factoriser :

E = 10x^2 - 5x + 15

E = 5 * 2x^2 - 5 * x + 5 * 3

E = 5(2x^2 - x + 3)

F = 4x^2 + 7x

F = x * 4x + x * 7

F = x(4x + 7)

G = 9x^2(x + 1) + 6x(5 + x)

G = 3x * 3x(x + 1) + 3x * 2(5 + x)

G = 3x[3x(x + 1) + 2(5 + x)]

G = 3x[3x^2 + 3x + 10 + 2x]

G = 3x(3x^2 + 5x + 10)

H = (11x - 3)^2 + (11x - 3)(5 + 9x)

H = (11x - 3)(11x - 3) + (11x - 3)(5 + 9x)

H = (11x - 3)(11x - 3 + 5 + 9x)

H = (11x - 3)(20x + 2)

H = (11x - 3) * 2(10x + 1)

H = 2(11x - 3)(10x + 1)
