    The product of zeroes of the polynomial \[d{{x}^{3}}+c{{x}^{2}}+bx+a\] is:

    A) \[\frac{d}{a}\]

    B) \[\frac{a}{d}\]

    C) \[-\frac{d}{a}\]

    D) \[-\frac{a}{d}\]

    Correct Answer: D

    Solution :

    [d] The given polynomial is
    \[p(x)=d{{x}^{3}}+c{{x}^{2}}+bx+a\]
    Now, product of zeroes
    \[=-\frac{\text{Constant term}}{\text{Coefficient of}\,{{x}^{3}}}=-\frac{a}{d}\]
