bonjour,

Factoriser :
C=12a-12ab
F=3 (2+x)+(2+x)×y
E= (3-2x)(5-x)-(3-2x)(7-4x)
G=(5+2x)(5-x)-(5+2x)​

Sagot :

Bonsoir,

C=12a-12ab=

12a( 1 -b)

F=3 (2+x)+(2+x)×y=

(2+x) ( 3 +xy)

E= (3-2x)(5-x)-(3-2x)(7-4x)

=(3-2x) ( 5-x -7+4x)

= (3-2x) ( 3x -2)

G=(5+2x)(5-x)-(5+2x)​

= (5+2x)  ( 5-x -1)

(5+2x) ( 4-x)
