x + 1)3x⁴ - 4x³ - 3x² -2x-1( 3x³ - 7x² + 4x - 6

    (-)   3x⁴ + 3x³

                    - 7x³ - 3x²

             (-)    - 7x³ - 7x²

                                 4x² - 2x

                          (-)    4x² + 4x  

                                         - 6x - 1

                                 (-)     - 6x - 6

                                                 5

Quotient = 3x³ - 7x² + 4x - 6

Remainder = 5

Verification:

Dividend = Divisor×Quotient+Remainder

(3x⁴ - 4x³ - 3x² - 2x - 1)

= (x + 1) × (3x³ - 7x² + 4x - 6) + 5

= x(3x³ - 7x² +4x - 6)+ 1(3x³- 7x²+4x - 6) + 5

= 3x⁴- 7x³ + 4x² - 6x + 3x³-7x² + 4x - 6 + 5 = (3x⁴ - 4x³ - 3x² - 2x - 1)

LHS = RHS

Hence Proved
