Conjugate Roots Theorem

Given a Polynomial Equation with Real Coefficients:

\[a_0+a_1x+a_2x^2+a_3x^3+\dots+a_{n-1}x^{n-1}+a_nx^n=0 \text{ where}\hspace{0.5em} a_0, a_1, a_2, a_3, \dots, a_{n-1}, a_n \in \mathbb{R}\]

If \(z\) is a complex root of the equation, then \(z^*\) is also a complex root of the equation.
