Write the polynomial with complex zeros

The video tutorial explains how to write the equation of a polynomial when given its zeros, including real, rational, irrational, and complex zeros. It emphasizes the importance of complex conjugates and demonstrates techniques to avoid fractional coefficients. The tutorial covers linear factorization, the difference of two squares, and handling complex zeros with multiplicity. The final section combines these concepts to form the complete polynomial equation.
