    Find a quadratic polynomial, whose sum and product of zeros are\[\frac{-10}{\sqrt{3}}\]and 7 respectively.

    A)  \[{{x}^{2}}+\frac{10}{\sqrt{3}}x+\frac{7}{\sqrt{3}}\]

    B)  \[\sqrt{3}{{x}^{2}}-10x+7\sqrt{3}\]

    C)  \[\sqrt{3}{{x}^{2}}+10x+7\sqrt{3}\]

    D)  \[{{x}^{2}}+10x+7\sqrt{3}\]

    Correct Answer: C

    Solution :

     Let a and p be the zeros of the required polynomial\[{{6}^{x}}\]. Given, \[{{x}^{3}}\]\['x'\] \[\text{(25}\times \text{7)cm}\] \[~(\text{2}\times \text{52}\times \text{73) cm}\] Hence, the quadratic polynomial is \[=(\text{25}\times \text{7})\text{(2}\times {{\text{5}}^{\text{2}}}\times {{\text{7}}^{\text{3}}}\text{) c}{{\text{m}}^{\text{2}}}\]
