    Another one i am unsure of: If a and b are roots of the equation x^2 + mx + n = 0, find the roots of nx^2 + (2n - m^2)x + n = 0 in terms of a and b.

    I have no idea how to do this question: If a and b are roots of the equation x^2 + 8x - 5 = 0, find the equation whose roots are a/b and b/a without finding a and b. I have to form a new equation to do this (ax^2 + bx + c = 0)
