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)
