Find an nth degree polynomial function with real coefficients satisfying the given conditions;
n=3; 3 and i are zeros; f(2)=15
How do you solve this equation...I am lost

Ii \(\displaystyle i\) is a root then \(\displaystyle -i\) is also a root.
So \(\displaystyle f(x)=k(x-3)(x-i)(x+i)\). Find \(\displaystyle k\) so \(\displaystyle f(2)=15\).
