Zeros of a function:
Given a polynomial f(x), this polynomial has roots such that it can be written as:
, in which a is the leading coefficient.
Has zeros −19 and −i
If -i is a zero, its conjugate i is also a zero. So
Output of 40 when x=1
This means that when . We use this to find the leading coefficient a. So
The polynomial is:
