this paper is insanely hard
1.) I can't quite get this one
2.) sqrt(3-6i)
3.) 4n-4n^2
4.) not a clue, I've never seen anything like this before, some help would be appreciated.
5.)x=1,x=(3-i),x=(3+i),x=(-1-2i),x=(-1+2i) [is it realistic we will get a quintic in the exam?]
need a break after solving that quintic, let me know how I've done if you have some time
