How do you write a polynomial with zeros: 2i, sqrt2, and 2? Precalculus Polynomial Functions of Higher Degree Zeros 1 Answer Shwetank Mauria Mar 9, 2016 #x^3-(2+sqrt2+2i)x^2+(2sqrt2+(2sqrt2+4)i)x-4sqrt2i# Explanation: The polynomial with zeros: #2i,sqrt2# and #2# is #(x-sqrt2)(x-2)(x-2i)# or #(x^2-sqrt2x-2x+2sqrt2)(x-2i)# or #(x^3-sqrt2x^2-2x^2+2sqrt2x-2ix^2+2sqrt2ix+4ix-4sqrt2i)# or #x^3-(2+sqrt2+2i)x^2+(2sqrt2+(2sqrt2+4)i)x-4sqrt2i# Answer link Related questions What is a zero of a function?
