J'APPLIQUE 14 12 Ca3 Compléter pour factoriser. a. 3x + 3y = .......X X + ........X y = b. 20x + 12 = x 5x + ..... X3 = 56 c. z2 + z= ..X + z X........ = .... A

bonsoir

3 x + 3 y = 3 ( x + y )

20 x + 12 =  4 ( 5 x + 3  )

z²  + z = z  ( z + 1 )

Bonsoir,

Exercice 12:

a. 3x + 3y = 3*x + 3*y = 3(x + y)

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

c. z² + z = z*z + z = z(z + 1)
