A splitting field of a polynomial p(X) over a field K is a field extension L of K over which p factors into linear factors
and such that the coefficients ai generate L over K. The extension L is then an extension of minimal degree over K in which p splits. It can be shown that such splitting fields exist and are unique up to isomorphism. The amount of freedom in that isomorphism is known to be the Galois group of p (if we assume it is separable).

Famous quotes containing the words splitting and/or field:
“Verily, chemistry is not a splitting of hairs when you have got half a dozen raw Irishmen in the laboratory.”
—Henry David Thoreau (1817–1862)
“Better risk loss of truth than chance of error—that is your faith-vetoer’s exact position. He is actively playing his stake as much as the believer is; he is backing the field against the religious hypothesis, just as the believer is backing the religious hypothesis against the field.”
—William James (1842–1910)
