Bonjour,

A = 2(x+8)

A = 2 * x + 2 * 8

A = 2x + 16

B = 3(x -2)

B = 3 * x + 3 * -2

B = 3x - 6

C = -4(8 + 2x)

C = - 4 * 8 - 4 * 2x

C = - 32 - 8x

C = - 8x - 32

D = -3(x - 7)

D = -3 * x - 3 * (-7)

D = -3x + 21

E = -4x(3x -2)

E = -4x * 3x -4x * (-2)

E = -12x² + 8x

F = (5x -1) * x

F = 5x * x - 1 * x

F = 5x² - x
