Hey guys,
I was doing some random questions from past papers, and I came across this question which I'm having trouble to do. It's from the HSC in 2000.
If anyone could help, it would be greatly apprecaited. Thanks.

The polynomial P(x) = x^3 + px^2 + qx + r has real roots, ROOT k, - ROOT K and α .
(i) Explain why α + p = 0.
(ii) Show that kα = r .
(iii) Show that pq = r .
