SUMMARY

This discussion focuses on solving a fourth order polynomial in Excel, specifically converting the equation from the form y=F(x) to x=F(y). The equation F(x)-y=0 represents a fourth degree polynomial in x, which can be solved to yield solutions of the form x=gi(y), where i ranges from 1 to 4. Excel can be utilized to find these roots using numerical methods or built-in functions.

PREREQUISITES
  • Understanding of polynomial equations, specifically fourth order polynomials.
  • Familiarity with Excel functions and numerical solving techniques.
  • Knowledge of how to manipulate equations algebraically.
  • Basic skills in using Excel for mathematical computations.

helo,

just wondering if anyone could tell me how to solve a fourth order polynomial in excel. i have a fourth order polynomial of form y=F(x), but i want it to be x=F(y)

I don't fully understand what you want. However F(x)-y=0 is a fourth degree equation in x, which is solvable. The solutions will be of the form x=gi(y), where i=1,2,3,4.
