Explications étape par étape

Bonsoir

Je suppose que tu voulais dire factoriser :

g(x) = 4x^2 - 8x + 4

g(x) = (2x)^2 - 2 * 2x * 2 + 2^2

g(x) = (2x - 2)^2

I(x) = (2x + 1)^2 - 9

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

I(x) = (2x + 1 - 3)(2x + 1 + 3)

I(x) = (2x - 2)(2x + 4)

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

I(x) = 4(x - 1)(x + 2)

j(x) = (x + 2)^2 - (x - 4)^2

j(x) = (x + 2 - x + 4)(x + 2 + x - 4)

j(x) = 6(2x - 2)

j(x) = 6 * 2(x - 1)

j(x) = 12(x - 1)
