Bonjour,

Factoriser chaque expression :

A= 9x-5x
B= 2x²+3x
C= 3y (y+1) - 4 (y+1)
D= 3a (2a+1) + (5+a) (2a+1)
E= (t-2) (3t+4) + (1+t) (t-2)

Bonjour,

Factoriser chaque expression :

A= 9x-5x

A= 4x

B= 2x²+3x

B= x(2x+3)

C= 3y (y+1) - 4 (y+1)

C= (y+1)(3y-4)

D= 3a (2a+1) + (5+a) (2a+1)

D= (2a+1)(3a+5+a)= (2a+1)(4a+5)

E= (t-2) (3t+4) + (1+t) (t-2)

E= (t-2)(3t+4+1+t)= (t-2)(4t+5)
