: The set of all these "valid" swaps forms a mathematical group, known as the Galois group of the polynomial. Galois' Theory Of Algebraic Equations

: Galois theory looks at how you can swap (permute) the roots of an equation without changing the algebraic relations they satisfy. This theorem establishes a bridge between two different

Galois theory is a major branch of abstract algebra that connects field theory and group theory to solve polynomial equations. It provides the definitive criteria to determine if a polynomial equation can be solved using (standard arithmetic plus root extractions) . 1. The Core Concept: Symmetry of Roots It provides the definitive criteria to determine if

: If the Galois group is "solvable" (meaning it can be broken down into specific smaller parts), then the equation can be solved by radicals. 2. The Fundamental Theorem of Galois Theory

The fundamental insight is that the roots of a polynomial exhibit .
