    The quadratic polynomial whose sum of zeroes is 3 and product of zeroes is \[-2\] is:                             (CBSE 2011)

    A) \[{{x}^{2}}+3x-2\]

    B) \[{{x}^{2}}-2x+3\]

    C) \[{{x}^{2}}-3x+2\]

    D) \[{{x}^{2}}-3x-2\]

    Correct Answer: D

    Solution :

    [d] Sum of zeroes,  \[S=3\]
    Product of zeroes, \[P=-2\]
    \[\therefore \]  Quadratic polynomial
    \[p(x)={{x}^{2}}-(S)x+P={{x}^{2}}-3x-2\]
