    A 13/9 Correct Answer Incorrect Answer
    B 15/7 Correct Answer Incorrect Answer
    C 11/5 Correct Answer Incorrect Answer
    D 10/3 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Sum = 5/2, product = 3/2 1/x₁² + 1/x₂² = (x₁² + x₂²)/(x₁x₂)² = [(sum)² – 2×prod]/(prod)² = [(25/4 – 3)/(9/4)] = (13/4)/(9/4) = 13/9.
