Galois theory answers the classical problem of why quintic and higher-degree polynomials generally do not have solutions by radicals, whereas quadratic, cubic, and quartic equations do.

Conditions: Motivational overview only; The statement is about general behavior of polynomial degrees, not a fully proved claim in this clip
