Homework Statement
Find a Polynomial function of degree 5 whose zeros are: 2, radical 7, and 5i

Multiplying roots
The Attempt at a Solution
Hello, well it's my first time at these forums so just following the template given. Thanks for any help by the way I'm just so confused.
I know that being given an imaginary number makes another root -5i automatically but the polynomial is a degree 5 with 5 roots. So my roots are (2, radical 7, 5i and -5i) I only have 4 and I don't really know any way to find the 5th.
I've already multiplied 5i and -5i to get one part of the polynomial but without the 5th root, I just can't finish. Anyone have any suggestions?
Thanks so much again.
