(3χ-2χ+1)÷(χ₃-3χ₂-χ-1)(3χ-2χ+1)÷(χ₃-3χ₂-χ-1)(3χ-2χ+1)÷(χ₃-3χ₂-χ-

(3χ-2χ+1)÷(χ₃-3χ₂-χ-1)
(3χ-2χ+1)÷(χ₃-3χ₂-χ-1)

(3χ-2χ+1)÷(χ₃-3χ₂-χ-1)
(3χ-2χ+1)÷(χ³-3χ²-χ-1)
=(χ+1)÷(χ³-3χ²-χ-1)
=x^4-3x³-x²-x+x³-3x²-x-1
=x^4-2x³-4x²-2x-1

(3χ-2χ+1)÷(χ³-3χ²-χ-1)
=(χ+1)÷(χ³-3χ²-χ-1)
=x^4-3x³-x²-x+x³-3x²-x-1
=x^4-2x³-4x²-2x-1
