How do i find the answer to this matrix?

First off, "answer to this matrix" doesn't make any sense. A matrix isn't a problem, it's an object, like a number or expression.
You're asked to compute the difference between two matrices. When you're given two matrices of same dimension (same number of rows and columns), the sum/difference of them is the matrix whose components are sums/differences of the corresponding components.
As a simple example,



In this case,

(1/x + 1)^2 + 6 (1/x + 1) +5
