Explications étape par étape

A = 16x + 4

A = 4(4x+1)

B = 9x -72x²

B= 9x(1 - 8x)

E = 24x + 30y - 18z

E = 6(4x + 5y - 3z)

F = 3x(4x - 6) +3x

F =3x(4x - 6 + 1)

F = 3x(4x - 5)

G = (x-5)(-3+4x)+6x(x-5)

G = (x-5)(-3+4x+6x)

G = (x-5)(-3+10x)

H = (x+7)(-4x+9)-x-7

H = (x+7)(-4x+9)-(x+7)

H = (x+7)(-4x+9-1)

H = (x+7)(-4x+8)

H =-4(x-2)(x+7)

I = (5x+3)² - (5x+3)

I = (5x+3)(5x+3-1)

I = (5x+3)(5x+2)

A = x² - 36

(a + b)(a - b) = a2 - b2 (identité remarquable)

A = (x+6)(x-6)

B = x² + 4x + 4

(a + b)2 = a2 + 2ab + b2 (identité remarquable)

B = (x + 2)²

C = x² - 16x + 64

(a - b)² = a² - 2ab + b² (identité remarquable)

C = (x - 8)²

D = 81x² - 36

(a + b)(a - b) = a2 - b2 (identité remarquable)

D = (9x - 6)²

E = 9x² + 30x + 25

(a + b)2 = a2 + 2ab + b2 (identité remarquable)

E = (3x+5)²

F = 49x² - 14x + 1

(a - b)² = a² - 2ab + b² (identité remarquable)

F =(7x - 1)²
