Te conviene reescribir esa función de este modo sacando factor común x²: f(x)=x²(x²-2) Ahora f(c)=0 si y solo si c²=0 o c²-2=0 Fíjate que c son las raíces.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
