    Which of the following is a cubic polynomial whose zeros are (-1), (-2) and (-3)?

    A)  \[{{p}^{3}}-6\]

    B)  \[{{p}^{3}}-6{{p}^{2}}+6\]

    C)  \[{{p}^{3}}+6{{p}^{2}}+11p+6\]

    D)  \[{{p}^{3}}-6{{p}^{3}}-11p-6\]

    Correct Answer: C

    Solution :

     Let\[16=8\times 2+0\]. If (-1), (-2) and (-3) are the zeros of\[\text{256}=\text{8}\times \text{32}+0\], then f (-1), f (-2) and f (-3) are all zero.
