For this case we have a polynomial with the following root:
5 - 7i
The first thing we must observe is that the root is a complex number.
When the root is a complex number, we always have the conjugate complex of this number, it is also a root of the polynomial.
Therefore, another root of the polynomial is given by:
5 + 7i
Answer:
other root of this polynomial is:
5 + 7i
