A 2 x 2 matrix has 2 rows and 2 columns
A specific 2 x 2 matrix a with no zero entries at all is [tex]\left[\begin{array}{cc}1&-2\\-3&6&\end{array}\right][/tex]
How to construct the matrix?
From the question, we understand that the matrix is a 2 x 2 matrix.
A 2 x 2 matrix is represented as:
[tex]\left[\begin{array}{cc}a&b\\c&d&\end{array}\right][/tex]
Also from the question we understand that the elements of the matrix are non-zero.
This means that:
[tex]a \ne 0\ , b \ne 0, \ c \ne 0, \ d \ne 0[/tex]
An example of such matrix is:
[tex]\left[\begin{array}{cc}1&-2\\-3&6&\end{array}\right][/tex]
Note that there are several matrices that fit the given construction requirement
