Question

Write a polynomial function using the given roots.
3+i, 2, and -4
(I need help understanding and helping getting the answer)

Answer 1

example if the roots is -4 then (x+4) is a factor
if (3 + i) is a root then -(3 + i) is also a root
when you multiply factors then you get the original polynomial
maybe I should start by saying when you set the polynomial equal to zero and solve then you get the roots.

let me know if you have any questions.

Answer 2

So wait step by step how do I get the answer?
