    Question

    'r' is one of the roots of equation (r -

    1)p2 - (5r + 2)p + 12 = 0 and sum of roots is (32/5), Determine the two roots of the equation.
    A 6, 2/5 Correct Answer Incorrect Answer
    B 5, 3/5 Correct Answer Incorrect Answer
    C 8, 6/7 Correct Answer Incorrect Answer
    D 12, 11/13 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ, Let another root is 'q'. So, r + q = [5r + 2]/[r - 1] = 32/5 So, 25r+10 = 32r - 32 Or, 7r = 42, r = 6 So, another roots is (32/5) - 6 = 2/5
