Explications étape par étape

Bonjour

Developper :

A = (3x - 2)(5 - x) - 4x(x + 6)

A = 15x - 3x^2 - 10 + 2x - 4x^2 - 24x

A = -7x^2 - 7x - 10

B = -3(2 - 2x)(6 - 2x)

B = -3(12 - 4x - 12x + 4x^2)

B = -36 + 16x - 12x^2

B = -12x^2 + 16x - 36

C = 2(x + 3)(5x + 1)

C = 2(5x^2 + x + 15x + 3)

C = 10x^2 + 32x + 6

D = -2(x^2 + 1)(x - 2)

D = -2(x^3 - 2x^2 + x - 2)

D = -2x^3 + 4x^2 - 2x + 4
