Question

Degree 3, zeros: 1,-3-i, find the remaining zeros

Answer 1

Since its to the 3rd degree, then there are 3 zeros, meaning that there's only one remaining zero. And since  "-i" is listed among the current zeros, then the remaining zero must include the opposite: +i so therefore the remaining zero is -3+i. Also its the most likely answer per the information given.

Answer:  -3+i
