------------------------------------
n=3
3 and 4i are zeros
f(1) = 68
------------------------------------


f%28x%29=a%28x-3%29%28x-%284i%29%29%28x-%28-4i%29%29
-
a%28x-3%29%28x-4i%29%28x%2B4i%29
a%28x-3%29%28x%5E2-16i%5E2%29
a%28x-3%29%28x%5E2%2B16%29
-
a%281-3%29%281%5E2%2B16%29=68
a%28-2%29%2817%29=68
a%28-34%29=68
a=-2
-
highlight%28f%28x%29=-2%28x-3%29%28x%5E2%2B16%29%29
and you can fully multiply that if you want.
