Question

 

a. 4x²-14x+44

b. 4x²-14x+44, R -130

c. 4x²+10x-40

d. 4x²+10x-40, R 134

Answer 1

We divide polynomials the same way we divide constants.

 

 

                       4x² - 14x - 40

            __________________

(x + 3) | 4x³ - 2x² + 2x + 2

             4x³ +12x²

             ________________

                   -14x² + 2x

                   -14x² + 42x

                  ______________

                              -40x + 2

                              -40x - 120

                             ____________

                                        122

 

 

Quotient = 4x² - 14x - 40

Remainder = 122
