    If the zeroes of the polynomial \[{{x}^{3}}-3{{x}^{2}}+x+1\]are \[\frac{a}{r},\] a and or, then the value of a is:

    A) 1

    B) -1        

    C) 2

    D) -3

    Correct Answer: B

    Solution :

    [b] Product of zeroes \[=\frac{a}{r}\cdot a\cdot ar=-1\]
    \[\Rightarrow \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,{{a}^{3}}=-1\Rightarrow a=-1\]
