Finding roots of polynomial
WebAny 3 3 numbers (a,b,c) (a,b,c) can be considered as the roots of the monic cubic polynomial P (x) = (x-a) (x-b) (x-c). P (x) = (x −a)(x−b)(x −c). Applying Vieta's formula to the polynomial, we get P (x)=x^3 P (x) = x3. WebWolfram Alpha is a great tool for finding polynomial roots and solving systems of equations.
