For the polynomial below, -1 is a zero.
f(x)=x^3 +5x^2 +17x +13
Express f(x) as a product of linear factors.
**
use synthetic division:
..-1..|....1.....5.....17.....13...............
........|.........-1.....-4...-13......
........|...1......4.....13.....0......
f(x)=(x+1)(x^2+4x+13)
function has one real and 2 non-real roots or zeros
