Bonsoir c'est important

Factoriser les expressions suivantes..

A= 4r+4t
B=7z+9z
C=3y^2+2y
D=4x( x + 2) +3( x +2)
E= -3y (y + 6) + 7 (y +6)
F= (x - 1)(5x +4) + (3 +x)(x - 1)

Merci d'avance.

Réponse:

A= 4× (r+t)

B= z× (7 +9)

C= 3×y×y + 2×y

= y × (3y +2)

D= (x+2) × (4x + 3)

E= (y+6) × (7 - 3y)

F= (x - 1) × (5x + 4 + 3 + x)

= (x+1) × (6x + 7)
Bonsoir
A=4(r+t)
B=z(7+9)
C=y(3y+2)
D=(x+2)(4x+3)
E=(y+6)(-3y+7)
F=(x-1)(5x+4+3+x)
=(x-1)(6x+7)
