Precalculus Polynomial Functions of Higher Degree Zeros 1 Answer Vinícius Ferraz May 26, 2017 #p(z) = z^4 - 3z^3 + 5z^2 - 27z -36# Explanation: #p(z) = (z - 4)(z + 1)(z - 3i)(z + 3i)# #= (z^2 -3z - 4)(z^2 + 9)# #= z^4 - 3z^3 -4z^2 + 9z^2 - 27z -36# Answer link Related questions What is a zero of a function?
