Given that the polynomial function has the given zero, find the other zeros.
f(x)= -3 is a zero.
------------------
Using synthetic division:
-3)....1....-3....-5....39
........1.....-6....13..|..0
Solve x^2 - 6x + 13 = 0
x = [6 +- sqrt(36 - 4*13)]/2
---
x = [ 6 +- sqrt(-16)]/2
---
x = [6 +- 4i]/2
------
x = 3 + 2i or x = 3 - 21
