If the matrix has real entries, the coefficients of the characteristic polynomial are all real.

That blurb sounds like you just merged the concept of the matrix with real life and other planets.

The matrix product of X and P is not hermitian, but has a real and imaginary part.

But the real glitch in the matrix?

The eigenvalues of the Hermitian matrix H are real quantities which have a physical interpretation as energy levels.

The easiest way to prove it is probably to consider A as a Hermitian matrix and use the fact that all eigenvalues of a Hermitian matrix are real.

Another example of a ring is the set of all square matrices of a fixed size, with real elements, using the matrix addition and multiplication of linear algebra.
