Step-by-step explanation:

Given:

P(x) = -3x³ + 4x² - 2x + 5

g(x) = x + 1

Long Division Method :

x + 1) -3x³ + 4x² - 2x + 5 (-3x² + 7x - 9

        -3x³  - 3x²

         ------------------------------

                     7x² - 2x + 5

                     7x²  + 7x

          --------------------------------

                                   -9x + 5

                                   -9x  - 9

             ----------------------------------

                                              14

Verification :

Dividend  =  ( quotient *  divisor )  +  Remainder

                = (-3x² + 7x - 9) * (x + 1) + 14

                = -3x³ - 3x² + 7x² + 7x - 9x - 9 + 14

                = -3x³ + 4x² - 2x + 5

Hope it helps!
