Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of1, and the given zeros. 3,-2+2i

Answer 1

The critical issue here is that for a polynomial with real coefficients complex roots occur in conjugate pairs,

Therefore your equation is (x-3)(x+2+2i)(x+2-2i)=(x-3)(x²+4x+8).

I will leave the last multiplication to you!
