Bonjour,

 

A = 4x²+4x+4 = 4(x²+x+1)

 

B = -5x²+10x+15 = 5(-x²+2x+3)

 

C = 9y²-3y+27 = 3(3y²-y+9)

 

D = 3y^3+y² = y²(3y+1)

 

J'espère que tu as compris

a+

 

 

A=4x²+4x+4

A=4(x²+x+1)

 

B=-5x²+10x+15

B=5(-x²+2x+3)

 

C=9y²-3y+27

C=3(3y²-y+9)

 

D=3ypuissance3+y²

D=y²(3y+1)

 

voilà :)
