The Fundamental Theorem of Algebra can be applied to a polynomial by factoring or finding its roots to determine the exact number of roots the polynomial has.
The Fundamental Theorem of Algebra states that a polynomial with degree n has exactly n complex roots (including repeats), so to determine the number of roots of a polynomial, you need to find its degree.
The Fundamental Theorem of Algebra states that a polynomial of degree "n" has exactly "n" complex roots, allowing us to determine the number of roots by identifying the degree of the given polynomial.
