Polynomials and polynomial functions. An alternative way of deriving the quadratic formula is via the method of Lagrange resolvents , [13] which is an early part of Galois theory. The Galois theory approach to analyzing and solving polynomials is to ask whether, given coefficients of a polynomial each of which is a symmetric function in the roots, one can "break" the symmetry and thereby recover the roots.
