Đáp án:
   x³-4x²-12x+27
= (x+3)(x²-7x+9)

   x²+7x-8
= x²-x+8x-8
= (x²-x)+(8x-8)
= x(x-1)+8(x-1)
= (x-1)(x+8)

   x²+4x+3
= x²+x+3x+3
= (x²+x)+(3x+3)
= x(x+1)+3(x+1)
= (x+1)(x+3)

16x-5x²-3
= -5x²+16x-3
= -5x²+15x+x-3
= -(5x²-15x)+1(x-3)
= -5x(x-3)+1(x-3)
= (x-3)(-5x+1)

2x.(3x-1)-6x.(x+1)-(3-8x)
= 6x²-2x-6x²-6x-3+8x
= -3

Super buồn
