Bonjour
Explications étape par étape
A = 2x + 2x (1-3x)
A = 2x(1+1-3x)
A = 2x(2-3x)
B = 16x^2-36
B = 16x^2 - 6^2
B = (4x+6)(4x-6)
C = (2x-1) (x-1)-3x (2x-1)
C = (2x-1)(x-1-3x)
C = (2x-1)(-2x-1)
D = (2x+3) (2x-1)+ 4x²-1
D = (2x+3)(2x-1)+(2x+1)(2x-1)
D = (2x-1)(2x+3+2x+1)
D = (2x-1)(4x+4)
D = (2x-1)*4(x+1)
D = 4(2x-1)(x+1)
