    Quadratic Equations

    The roots of a quadratic equation 3x^2 √24 x -2 = 0 are m and n. Without using a calculator,

    i) show that 1/m + 1/n = - 6

    ii) find the value of 4/m 2/n in the form a b

    I have already found that sum of roots, m + n = 24 / (3)
    And product of roots = -2/3
    And proved part i)

    Can you help me with part ii) ? The answer is 108 √6
    Thanks

    First thing to do is find m and n using the quadratic formula.

    Do you know it?

    Also what is this symbol?
