Comprehensive presentation of the "Theorem of the Day", starting with a statement of this theorem.
The Fundamental Theorem of Algebra : The polynomial equation of degree n:
z^n + a_1 z^(n−1) + . . . + a_(n−1)z + a_n = 0,
with n ≥ 1 and with the a_i belonging to C, the complex numbers, has a solution in C. As a consequence, the polynomial can be factorised as (z − α1)(z − α2) · · · (z − αn), where the αi are again in C and are precisely the roots of the polynomial.
