Sagot :

Bonjour,

G = 3(2 + 3x) - (3x - 7)(2 + 3x)

G = (2 + 3x)[(3 - (3x - 7)]

G = (2 + 3x)(3 - 3x + 7)

G = (2 + 3x)(-3x + 10)

H = (5x - 4)(2x + 1) - (5x - 4)(4x - 3)

H = (5x - 4)[(2x + 1) - (4x - 3)]

H = (5x - 4)(2x + 1 - 4x + 3)

H = (5x - 4)(-2x + 4)

J = (1 + 6x)²- (1 + 6x)(2 - 5x)

J = (1 + 6x)[(1 + 6x) - (2 - 5x)]

J = (1 + 6x)(1 + 6x - 2 + 5x)

J = (1 + 6x)(x - 1)
