Bonsoir,

22)

A = x * 12

A = 12x

B = 1 * y

B = y

C = 0 * x

C = 0

D = 2y * 7

D = 14y

E = 2 * x * 3x

E = 2x * 3x

E = 6x²

F = y * 4 * (2 * y - 1)

F = y * 4 * (y - 1)

F = 4y * (y - 1)

F = 4y² - 4y

24)

A = x * (- 9) * 2

A = - 9x * 2

A = - 18x

B = 1,5 * y * (- 8)

B = 1,5y * (- 8)

B = - 12

C = x * (- 4) * (- x ) * 2

C = - 4x * - 2x

C = 8x²

D = - 2y² * (- 15) * 2y

D = 30y² * 2y

D = 60y³
