FAQ
Frequently Asked Questions
It is now rare. Most content is taught under 'Abstract Algebra' or 'Polynomials and Galois Theory'.
The 'theory of equations' is the broader historical field. Galois theory is a specific, revolutionary framework within it that uses group theory to characterise solvability.
Yes, quadratics are part of its scope, but the phrase typically implies a general, systematic study covering higher-degree polynomials.
Almost never. Engineers and physicists use 'root-finding' or 'numerical methods'. The term is purely mathematical and historical.
The branch of algebra concerned with the properties of polynomial equations and methods for finding their roots.
Theory of equations is usually formal, academic, historical mathematics in register.
Theory of equations: in British English it is pronounced /ˈθɪəri əv ɪˈkweɪʒənz/, and in American English it is pronounced /ˈθiːəri əv ɪˈkweɪʒənz/. Tap the audio buttons above to hear it.
