WebbNewton's identities, also known as Newton-Girard formulae, is an efficient way to find the power sum of roots of polynomials without actually finding the roots. If x_1,x_2,\ldots, x_n x1,x2,…,xn are the roots of a polynomial equation, then Newton's identities are used to find the summations like \displaystyle \sum_ {i=1}^n x_i^k=x_1^k +x_2^k ...
