Given:   a(x)  = x⁵ + 2x⁴ - x³  + 2  , b(x) = x³ + 3   a(x) = b(x)q(x) + r(x)

To find : q(x) & r(x)

Solution:

a(x)  = x⁵ + 2x⁴ - x³  + 2

b(x) = x³ + 3

                 x²  + 2x - 1

x³ + 3   _|   x⁵ + 2x⁴ - x³  + 2  |_

                  x⁵                 + 3x²

                 _______________

                          2x⁴ - x³  - 3x²  + 2

                          2x⁴                   + 6x

                                 ________________

                                          -3x² - 6x + 5

 

a(x)  = b(x)q(x)  +  r(x)

x⁵ + 2x⁴ - x³  + 2 = ( x³ + 3)  (x²  + 2x - 1)  + (  -3x² - 6x + 5)

q(x) = x²  + 2x - 1

r(x) =  -3x² - 6x + 5
