Sagot :
Bonjour
Facteur commun
A = (x+1)(x+1+3x+1) = (x+1)(4x+2)
B =(2x+1)(2x+1-x-3) = (2x+1)(x-2)
Identité remarquable (a+b)² =a²+b²+2ab ou (a-b)² =a²+b²-2ab
C = (x+6)²
D = (2x-10)²
identité remarquable a²-b² =(a-b)(a+b)
E = (2-8x)(2+8x)
F =((2x+1-5)(2x+1+5) = (2x-4)(2x+6)
G = (3x-4-6x-1)(3x-4+6x+1) = (-3x-5)(9x-3)
