svlad2 [7]

Answer:

The answer to your question is below

Step-by-step explanation:

5)                                2x² -7x + 34

                       x + 5   2x³ + 3x² - x + 1

                                 -2x³ -10x²

                                   0   - 7x² - x

                                        +7x² +35x

                                           0   +34x + 1

                                                 -34x - 170

                                                    0   - 160

Quotient = 2x² - 7x + 34

Remainder = -160

6)                                       2x² - 3x  + 1

                             3x + 1   6x³ - 7x² + 0x + 2

                                         -6x³ -2x²

                                          0    -9x² + 0x

                                                +9x² +3x

                                                   0   +3x + 2

                                                        - 3x - 1

                                                           0  + 1

Quotient = 2x² - 3x + 1

Remainder = 1
