The degree of the polynomial is 2

How to determine the degrees?

The root of the polynomial is given as:

Root = x - 3i

The above expression is a complex root.

This means that the conjugate is also a root of the polynomial

So, we have

Roots = x - 3i and x + 3i

Multiply the roots

f(x) = (x - 3i)(x + 3i)

This gives

f(x) = x^2 + 9

The degree of the above equation is 2 i.e. the highest power

Hence, the degree of the polynomial is 2
