Please help!! I do not understand any of this!!

Form a polynomial f(x) with real coefficients having the given degree and zeros.
Degree 4; zeros: 2, multiplicity 2; 3i

1 answer

Iam not certain what you mean by multiplicity.

I see the roots as (x-2)(x-2)(x-3i)(x+3i)

that is degree four,multiple roots at 2, root at 3i, and -3i, and all real coefficients.
