Step-by-step explanation:
Given the 2 x 2 matrix![\left[\begin{array}{ccc}ab\\cd\\\end{array}\right]](/tpl/images/0286/1352/79c37.png)
Then the determinant = ad - bc
Hence for![\left[\begin{array}{ccc}1&7\\0&-3\\\end{array}\right]](/tpl/images/0286/1352/8600c.png)
determinant = (1 × - 3) - (7 × 0) = - 3 - 0 = - 3
