If `A=[(2,-1),( 3, 2)]` and `B=[(0, 4),(-1, 7)]` , find `3A^2-2B+I` .

Explanation

To solve the problem, we need to find the expression \(3A^2 - 2B + I\) where:

- \(A = \begin{pmatrix} 2 & -1 \\ 3 & 2 \end{pmatrix}\)
- \(B = \begin{pmatrix} 0 & 4 \\ -1 & 7 \end{pmatrix}\)
- \(I\) is the identity matrix of the same order as \(A\) and \(B\), which is \(I = \begin{pmatrix} 1 & 0 \\ 0 & 1 \end{pmatrix}\)
