1. Réponse nathalienouts
F= x²+3x
F = x(x+3)
G= 6x-3x²
G = 3x(2-x²)
H= 4x²+8x+4 identité remarquable (a+b)² = a²+2ab+b²
H = (2x)²+2*2*2x+2²
H = (2x+2)²
I = -64+16x² identité remarquable a²-b² = (a+b)(a-b)
I = (4x)²-8²
I = (4x+8)(4x-8)
J= 4- (x+2)² idem
J = 2²-(x+2)²
J = (2+x+2) ( 2-x-2)
J = (x+4)(-x)
