For large matrices, the determinant can be calculated using a method called expansion by minors. This involves expanding the determinant along one of the rows or columns and using the determinants of smaller matrices to find the determinant of the original matrix.
This is not a “trick” question. We can actually find the value of [latex]x[/latex] such that when we apply the formula we get [latex]-12[/latex]. Get the determinant of the given matrix then set it equal to [latex]-12[/latex]. By doing so, we generate a simple linear equation that is solvable for [latex]x[/latex].
