Identify the dividend and the divisor of the rational expression,x4+2x3−x2−2x+5,x−1

Given:
There is an expression given as below
[tex]x^4+2x^3−x^2−2x+5,x−1[/tex]Required:
We need to identify the the dividend and the divisor of the rational expression
Explanation:
By division algorythm
The maximum power of Dividend is always greater or euqal to the power of Divisor so here
[tex]x-1[/tex]is divisor and
[tex]\begin{equation*} x^4+2x^3−x^2−2x+5 \end{equation*}[/tex]is dividend
Final answer:
Option B
