Question

Evaluate the determinant for the following matrix: [-5 1, 1 4]

Answer 1

The matrix given is $\left[\begin{array}{ccc}-5&1\\1&4\end{array}\right]$

To find determinant $\left[\begin{array}{ccc}a&b\\c&d\end{array}\right]$ we do $ad-bc$

So, the determinant of the given matrix is
$(-5)(4)-(1)(4) = -20 - 4 = -24$

Answer 2

Answer: -24
