    Question

    If x and y are the roots of x2 + x + 3 = 0,

    then (x11 + y11)/(x-11 + y-11) is equal to:
    A (3)^11 Correct Answer Incorrect Answer
    B -(3)^11 Correct Answer Incorrect Answer
    C (2)^17 Correct Answer Incorrect Answer
    D Cannot be determined Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    => (x11 + y11)/(x-11 + y-11) => (x11 + y11)/(1/x11 + 1/y11) => (x11 + y11)/{(x11 + y11)/(xy)11} => (xy)11 Product of root = c/a (xy) = (3)11
