Réponse:
I=25-36a² =(5) ²- (6a)²
I=(5+6a)(5-6a)
H=9x²- 30x + 25=(3x)²- 2(3x)(5) + (5)²
H=(3x - 5)²
J=(4x-3)²- 1 =(4x-3-1)(4x-3+1)
J=(4x-4)(4x-2) = 8(x-1)(x-1)
J= 8(x-1)(x-1)
E=(3x-1) - (3x-1)² = (3x-1)(1-3x+1)
E= -3x(3x-1)
F= x²+8x+16 = x²+ 2(x)(4) + (4)²
F= (x+4)²

J = 6x puissance 2
E = (3x - 1) - (9x - 1) = -6x (je suis pas sûr)
F = 8x + 16
