Bonjours pouvez vous m'aider svp ?Factoriser les expressions suivantes : A = (3 x – 1) (x – 8) + (2 x +4) (x - 8) B = (x - 5) (x + 2) - (x – 5) (3 x + 1) C = 7

Question
Bonjours pouvez vous m'aider svp ?Factoriser les expressions suivantes :
A = (3 x – 1) (x – 8) + (2 x +4) (x - 8)
B = (x - 5) (x + 2) - (x – 5) (3 x + 1)
C = 7 x2 – 21 x D = 5 x2 + 15 x
E = 4 x2 + x
F = (x + 2) (x + 5) - 3 (x + 5)
G= x (2 x + 3)- 7 (2 x+3)
H = 2 x + 3 + 5 x (2 x + 3)
I = 2 x + 1 + 5 x (2 x + 1) – 3 x (2 x + 1)
J = (2 x – 5)2 - (2 x – 5) (x + 2)
K = (x - 8) + x - 8
A = (3 x – 1) (x – 8) + (2 x +4) (x - 8)
B = (x - 5) (x + 2) - (x – 5) (3 x + 1)
C = 7 x2 – 21 x D = 5 x2 + 15 x
E = 4 x2 + x
F = (x + 2) (x + 5) - 3 (x + 5)
G= x (2 x + 3)- 7 (2 x+3)
H = 2 x + 3 + 5 x (2 x + 3)
I = 2 x + 1 + 5 x (2 x + 1) – 3 x (2 x + 1)
J = (2 x – 5)2 - (2 x – 5) (x + 2)
K = (x - 8) + x - 8

Bonjour!
A= (x-8)(5x+3)
B= - (x-5)(2x-1)
C= 7x(x-3)
D= 5x(x+3)
E= x(4x+1)
F= (x+5)(x-1)
G= (2x+3)(x-7)
H= (5x+1)(2x+3)
I= (2x+1)2
J= (2x-5)(x-7)
K= 2(x-8)
