Bonjour,

Écrire sans parenthèse puis réduire

A=8x+(2x-3)

A = 8x + 2x - 3

A = 10x - 3

B=5x-(x-4)

B = 5x - x + 4

B = 4x + 4

C=6x(x-5)

C = 6x² - 30x

Hello :)

A = 8x + (2x - 3)

A = 8x + 2x - 3

A = 10x - 3

B = 5x - (x - 4)

B = 5x - x + 4

B = 4x + 4

C = 6x(x - 5)

C = 6x * x - 6x * 5

C = 6x² - 30x

Bonne journée :)
