Abegg's rule is sometimes ref... | https://en.wikipedia.org/wiki/Abegg's_rule |

In mathematics , Abel's irreducibility theorem , a field theory result described in 1829 by Niels Henrik Abel , [ 1 ] asserts that if f ( x ) is a polynomial over a field F that shares a root with a polynomial g ( x ) that is irreducible over F , then every root of g ( x ) is a root of f ( x ). Equivalently, if f ( x )... | https://en.wikipedia.org/wiki/Abel's_irreducibility_theorem |
