    If the sum of the zeros of the polynomial \[\text{f(x)}=({{\text{k}}^{\text{2}}}-\text{14}){{\text{x}}^{\text{2}}}-\text{2x}-\text{12}\]is 1, which is one of the possible values of 'k' ?

    A)  \[\sqrt{14}\]                     

    B)         -14

    C)  2           

    D)         -4

    Correct Answer: D

    Solution :

     \[\therefore \] \[={{2}^{2}}\times {{3}^{2}}\times 5\times 7\times 11\times 13=180180\]             \[\therefore \](Given) \[H.C.F.=\frac{\text{Product of the numbers}}{L.C.M.}\]              \[\text{5474}=\text{2}\times \text{7}\times \text{17}\times \text{23}\]
