Question

Find a fourth-degree polynomial function f(x) with real coefficients that has -2,2, and i as zeros and such that f(3)=150

Answer 1

I will give you a hint since x=-2 is a zero then x+2 is a factor
so if x=2 is a zero then what else is a factor?
and if x=i is a zero then another zero must be what in order for us to have real coefficients?
