Aidez moi SVP :( factoriser: A=6x-3 B= 4x²+6x C= 9x²-12x+4 D= 4x² - 64 J= (x-1)²- 4

A=6x-3
A = 3 (2x - 1)

B= 4x²+6x
B = 2x (2x + 3)

C= 9x²-12x+4
C = (3x - 2)²

D= 4x² - 64 
D = 4 (x² - 16)

J= (x-1)²- 4 
J = (x - 1 - 2) (x - 1 + 2)
J = (x -3) (x + 1)

Bonsoir,

A=6x-3
A = 3(2x-1)

B= 4x²+6x
B= 2x(2x+3)

C= 9x²-12x+4
C = (3x)²-2*2*3x+2²   identité remarquable
C = (3x-2)²

D= 4x² - 64 
D = (2x)²-8²    identité remarquable
D = (2x+8) (2x-8)

J= (x-1)²- 4 
J =(x-1)² - 2²  identité remarquable
J= (x-1+2) (x-1-2)
J = (x+1) (x-3)
