Bonjour je dois factoriser mais je n'y arrives pas merci de bien vouloir m'indiquer la réponse ​

bonsoir

Factoriser :

F = x^2 + 10x + 25

F = x^2 + 2 * x * 5 + 5^2

F = (x + 5)^2

G = (x + 5)^2 - 4

G = (x + 5)^2 - 2^2

G = (x + 5 - 2)(x + 5 + 2)

G = (x + 3)(x + 7)

H = (x - 1)^2 + (x - 1)(x + 3)

H = (x - 1)(x - 1 + x + 3)

H = (x - 1)(2x + 2)

H = (x - 1) * 2(x + 1)

H = 2(x - 1)(x + 1)

I = 25x^2 - 20x + 16

I = (5x)^2 - 2 * 5x * 2 + 2^2 + 12

I = (5x - 2)^2 + 12

J = 18x^2 + 24x + 8

J = 2(9x^2 + 12x + 4)

J = 2[(3x)^2 + 2 * 3x * 2 + 2^2]

J = 2(3x + 2)^2
