Olá,

se a matriz A=(aij)2x2, ou seja, quadrada de ordem 2 (linhas e colunas = 2), temos a sua matriz genérica:

A=  \left(\begin{array}{ccc}a_{11}&a_{12}\\a_{21}&a_{22}\\\end{array}\right)\\\\
aij=3i-2j\\\\
A=  \left(\begin{array}{ccc}3\cdot1-2\cdot1&3\cdot1-2\cdot2\\3\cdot2-2\cdot1&3\cdot2-2\cdot2\\\end{array}\right)\\\\\\
\large\boxed{\boxed{A=  \left(\begin{array}{ccc}1&-1\\4&~~2\\\end{array}\right)}}\\.

Tenha ótimos estudos ^^
