Analyzing the Galois Groups of Fifth-Degree and Fourth-Degree Polynomials
Jesse Berglund · Journal of international women's studies · 2011
It is known that the general equations of fourth-degree or lower are solvable by formula and general equations of fifth-degree or higher are not. To get an understanding of the differences between these two types of equations, Galois theory and Field theory will be applied. The Galois groups of field extensions will be analyzed, and give the solution to the query “What is the difference between unsolvable fifth-degree equations and fourth-degree equations?”
