Question
Bonjour, comment factoriser :
A = (9x + 1)*2 + 9x + 1
B = (7x - 3)*2 + 7x - 3
C = 1 + 3x + (3x + 1)*2
D = x - 5 + (x - 5)*2
A = (9x + 1)*2 + 9x + 1
B = (7x - 3)*2 + 7x - 3
C = 1 + 3x + (3x + 1)*2
D = x - 5 + (x - 5)*2

Bonjour,
factoriser :
A = (9x + 1)² + 9x + 1
A= (9x+1)(9x+1 + 1)
A= (9x+1)(9x+2)
B = (7x - 3)² + 7x - 3
B= (7x-3)(7x-3 + 1)
B= (7x-3)(7x-2)
C = 1 + 3x + (3x + 1)²
C= (3x+1)( 1 + 3x+1)
C= (3x+1)(3x+2)
D = x - 5 + (x - 5)²
D= (x-5)( 1 + x-5)
D= (x-5)(x-4)
