Bonjour

Développer les expressions suivantes :

A = (-3+ y) x 9
A = -3 * 9 + y * 9
A = -27 + 9y

D=-8(9-7x)
D = -8 * 9 - 8 * (-7x)
D = -72 + 56x


B=-6(2x - 7)
B = -6 * 2x - 6 * (-7)
B = -12x + 42

E = -8z(4 - 32)
E = -8z * 4 - 8z * (-32)
E = -32z + 256z

C = (3t+ 2) x 8
C = 3t * 8 + 2 * 8
C = 24t + 16

F = 3y(-4 + 6y)
F = 3y * (-4) + 3y * 6y
F = -12y + 18y^2
