????????? x=3+[sqrt(3/3)]i ?????????
3/3=1 & sqrt(1)=1
so yu hav x=3+i
tu du math with this, best tu konvert it tu polar form...
3+i become leng=3.1622776601683795 & angel=18.43494882292 deg
then x^2 become...leng=10 & angel=36.86989764584
3x^2...leng=30 & angel the same
-6x...leng=-6*10=-60 & angel the same...kan look at it as leng=60 & add 180 deg tu angel
