a) \(x⁴ − 2x³ + 2x − 1 = (x² − 1)(x² − 2x + 1) + 4x − 2\)

\(⇒ (x⁴ − 2x³ + 2x − 1) : (x² − 1) = x² − 2x + 1\) dư \(4x − 2\)

b) \(x³ − 3x² + 3x − 2 = (x² − x + 1)(x − 2)\)

\(⇒ (x³ − 3x² + 3x − 2) : (x² − x + 1) = x − 2\)

c) \(8x³ − 6x² − 5x + 3 = (4x + 3)(2x² − 3x + 1)\)

\(⇒ (8x³ − 6x² − 5x + 3) : (4x + 3) = 2x² − 3x + 1\)

d) \(2x³ − 3x² + 3x − 1 = (x² − x + 1)(2x − 1)\)

\(⇒ (2x³ − 3x² + 3x − 1) : (x² − x + 1) = 2x − 1\)
