Question 168291: find additional zeros for a function with degree 5 and the following zeros 2,
-i, 1+i
Answer by Fombitz(32388) (Show Source):
You can put this solution on YOUR website! Whenever a polynomial has complex roots, the roots come in complex conjugates pairs.
So if (0-i) is a root, then so is (0+i).
and if (1+i) is a root, then so is (1-i).
The five roots are then 2,i,-i,1+i,1-i.
