    *PLS HELP!* Roots & Coefficients in Quadratic Equations

    I'm not sure how to solve this one problem: "If α and β are roots of the equations x²+mx+n=0, find the roots of nx²+(2n-m²)x+n=0 in terms of α and β." I would really appreciate it if someone could show me how to do it. I'm like 9 weeks behind on work lol. Thanks in advance! :D
