Question
Find the value of each determinant.$$\left|\begin{array}{rr}{-2} & {4} \\ {3} & {-6}\end{array}\right|$$
Step 1
In a 2x2 matrix, the elements are usually denoted as follows: $$ \left|\begin{array}{rr}{a} & {b} \\ {c} & {d}\end{array}\right| $$ In this case, we have a = -2, b = 4, c = 3, and d = -6. Show more…
