Solution

Using division algorithm, we have

`f(x)= g(x)xxq(x)+ r(x)`

`x^5- 4x^3 + x^2+ 3x +1 = (x^3 - 3x +1)(x^2 -1)+ 2`

`x^5 - 4x^3+ x^2 + 3x + 1= x^5 - 3x^2 - x^3 + 3x -1 +2`

`x^5 -4x^3 + x^2 +3x +1 = x^5 - 4x^3 + x^2 + 3x +1`

`x^5 - 4x^3 + x^2 + 3x +1 = x^5 - 4x^3 + x^2 + 3x + 1`

Hence an example for polynomial `f(x)`, g(x), q(x) and  r (x) satisfying  `f(x)= g(x)xxq(x)+ r (x)` are

`f(x)= x^5 - 4 x^3 + x^2 + 3x +1 `

`g(x)= (x^2 - 3x + 1)`

`q(x)= (x^2-1)`

`r(x)= 2`
