Vieta's formula relates the coefficients of polynomials to the sums and products of their roots, as well as the products of the roots taken in groups.
For example, if there is a quadratic polynomial , it will have roots of and , because . Vieta's formula can find the sum of the roots and the product of the roots without finding each root directly. While this is fairly trivial in this specific example, Vieta's formula is extremely useful in more complicated algebraic polynomials with many roots or when the roots of a polynomial are not easy to derive. For some problems, Vieta's formula can serve as a shortcut to finding solutions quickly knowing the sums or pr
