    When the polynomial \[\mathbf{f(x)=}{{\mathbf{x}}^{\mathbf{4}}}\mathbf{+3}{{\mathbf{x}}^{\mathbf{3}}}\mathbf{-2}{{\mathbf{x}}^{\mathbf{2}}}\mathbf{+x-1}\] is divided by \[\left( \mathbf{x-2} \right)\] what will be the remainder?

    A)  17                  

    B)  33         

    C)  23                               

    D)  29

    Correct Answer: B

    Solution :

    (b): \[f\left( 2 \right)={{2}^{4}}+3\times {{2}^{3}}-2\times {{2}^{2}}+2-7\] \[=16+24-8+2-1-19\therefore Remainder=33\]
