Explications étape par étape

Bonsoir,

Exercice 43

A= 4(x+3)

B= 3(2x-5)

C= 7(3x-x)

D= 2(2-5x)

E= 3(3x² +2)

F= x(x -4)

G= 2(x+1)

H = x(x+1)

I = x(4x +3x)

Exercice 44

a)

A = 3(x+2)

D= 6(2+3x)

G= 4x(x -5)

R = 5(x-2)

E = 10( 5-x)

H = x(3x -5)

C= x(4+9)

F = x(x+7)

I= 3(4x² -1)

b)

A = 7(x+1)

D = 10 (1-2x)

B = 3x(x+1)

E = x(4x -9)

C= 9x(2 -1)= 9x

F = 5x(2x + 7)
