If `A =[(1,-1),(2,5)]` and `B=[(-2,2),(3,1)]` then find the values `A^2-2B^-`

Explanation

To solve the problem, we need to find the value of \( A^2 - 2B \) where \( A = \begin{pmatrix} 1 & -1 \\ 2 & 5 \end{pmatrix} \) and \( B = \begin{pmatrix} -2 & 2 \\ 3 & 1 \end{pmatrix} \).

### Step 1: Calculate \( A^2 \)

To find \( A^2 \), we need to multiply matrix \( A \) by itself:

\[
A^2 = A \times A = \begin{pmatrix} 1 & -1 \\ 2 & 5 \end{pmatrix} \times \begin{pmatrix} 1 & -1 \\ 2 & 5 \end{pmatrix}
