I was confused as to how to do the following, so any explanations would be greatly appreciated!

If A is an n by n matrix, show that the constant term of p sub A of x is (-1)^n * the determinant of A.

Sorry, I also should have mentioned that p sub A of x represents the characteristic polynomial of A, which is the determinant of xI sub n - A
