a. Compare the determinants using a cofactor expansion across the first row.

b. compute the determinant by a cofactor expansion down the second column.

$$\left|

\begin{array}{rrr}

3&0& 4\\

2&3& 2\\

0&5&-1\\

\end{array}

\right|$$

ok I accually start this class tomorro but thot I would try some basic stuff

already stuck...
