EXERCICE 2 Factoriser les expressions suivantes A = 5x + 5a B = 3x + 3y F=12y + 16 G=20x+100 C=xy + 4x H=16-4a D=4a+a I= 3xy-6yz E = 9+ 3x J= 4x + 12x

Merci d'avance ;)​

Réponse:

A = 5( x + a )

B = 3 ( x + y )

C = x ( y + 4 )

D = a ( 4 + 1 )

E = 3 ( x + 3 )

F = 4 ( 3y + 4 )

G = 20 ( x + 5 )

H = 4 ( 4 - a )

I = 3y ( x - 2z )

J = 4x ( 1 + 3 )
