SUMMARY

The discussion focuses on solving cubic (x^3) and quartic (x^4) equations using Horner's method, while also acknowledging Abel's impossibility theorem, which states that there are no explicit algebraic solutions for polynomial equations of degree five or higher. Participants mention that while general formulas exist for cubic and quartic equations, alternative techniques can be employed for higher-degree polynomials. A resource from Wolfram Library is provided for further exploration of quintic equations.

PREREQUISITES
  • Understanding of polynomial equations, specifically cubic and quartic forms.
  • Familiarity with Horner's method for polynomial evaluation.
  • Knowledge of Abel's impossibility theorem regarding polynomial solvability.
  • Basic skills in algebraic manipulation and equation solving.
NEXT STEPS
  • Research the general formulas for solving cubic and quartic equations.
  • Explore advanced techniques for solving quintic equations, such as numerical methods.
  • Study the implications of Abel's impossibility theorem on polynomial equations.
  • Investigate additional resources on polynomial equation solving techniques, including the Wolfram Library.
USEFUL FOR

Mathematicians, educators, students studying algebra, and anyone interested in advanced polynomial equation solving techniques.

Equations that have x^3 or x^4 etc...,are solved with method of Horner.
There is quicker way to solve an equation like that? (except factorization).

Thank you a lot!

Well, there's a general formula for solving cubic and quartic equations. However, Abel's impossibility theorem states that there cannot be explicit algebraic formulas for the general solutions to degree 5 and higher polynomials.

But some techniques can help you solve such equations...

For example, this page discuss the solvability of quintic equations: http://library.wolfram.com/examples/quintic/
