    Question

    If the roots of the quadratic equation 7y┬▓ + 5y + 9 = 0

    are ╬▒ and ╬▓, then find the value of [(1/╬▒) + (1/╬▓)].
    A 1/2 Correct Answer Incorrect Answer
    B -2/3 Correct Answer Incorrect Answer
    C 4/9 Correct Answer Incorrect Answer
    D -5/9 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Given: ╬▒, ╬▓ are the roots of 7y┬▓ + 5y + 9 = 0. We know: ╬▒ + ╬▓ = -b/a = -5/7 ╬▒╬▓ = c/a = 9/7 Now, Thus, (1/╬▒) + (1/╬▓) = -5/9 .
