Bonjour,

Exercice 35

A = -3(x + 5) = -3x - 15

B = -7(t - 3) = -7t + 21

C = 4(-5u - 1) = -20u - 4

D = 9(-2 - 7v) = -18 - 63v

E = 4w(10 - w) = 40w - 4w²

F = -x(4x - 9) = -4x² + 9x

Exercice 36

a. 4(3x-5) = + 12x - 20

b. -4(3x-5) = - 12x + 20

c. 4(-3x-5) = - 12x - 20

d. -4(-3x+5) = + 12x - 20

e. -4(-3x-5) = + 12x + 20
