    If sum of zeroes of \[q\left( x \right)=k{{x}^{2}}+2x+3k\]is equal to their product, then k =

    A) 2/3

    B) 1/3

    C) -2/3

    D) -1/3

    Correct Answer: C

    Solution :

    Given, \[q\left( x \right)=k{{x}^{2}}+2x+3k\]
     Sum of zeroes = equal to their product
                            \[\frac{-2}{k}=\frac{3k}{k}\]
                            \[k=-2/3\]
