Credit / Debit Card In specific, the minimal polynomial p(t) divides the characteristic polynomial of T. The dimension of the null space of the above matrix is 2, hence it has a basis consisting of the eigenvectors of the matrix, hence it is diagonalizable, hence it's minimal polynomial spilts into distinct linear factors, hence it cannot be $x^2(x^2-4)$, hence the answer is $x(x^2-4)$. The method is very useful for finding the factored form of the four term polynomials. There are different semantic interpretations of whether the degree of a polynomial is the same as the order of the polynomial. Would the reflected sun's radiation melt ice in LEO? How does minimal polynomial divide characteristic polynomial of matrix? It's fulfilling to see so many people using Voovers to find solutions to their problems. If n is odd, you can go from one polynomial to the other by changing all their coefficients to opposite numbers (i.e., changing all of their signs). All the distinct roots of the characteristic polynomial are also the roots of the minimal polynomial, hence the minimal polynomial has roots $0,2,-2$ When and how was it discovered that Jupiter and Saturn are made out of gas? In Linear algebra, the characteristic polynomial and the minimal polynomial are the two most essential polynomials that are strongly related to the linear transformation in the n-dimensional vector space V. In this article, we will learn the definition and theorems of a minimal polynomial, as well as several solved examples.
