Compute the determinant using a cofactor expansion across the first row. Also compute the determinant by a cofactor expansion do
V125BC [204]

Answer:

Step-by-step explanation:

It is given that

\Delta=\begin{vmatrix}3&0&3\\2 &3&3\\0 &4&-2\end{vmatrix}

By cofactor expansion across the first row, we get

\Delta=a_{11}C_{11}+a_{12}C_{12}+a_{13}C_{13}

\Delta=3\left[(-1)^{1+1}\begin{vmatrix}3&3\\4&-2\end{vmatrix}\right]+0\left[(-1)^{1+2}\begin{vmatrix}2&3\\0&-2\end{vmatrix}\right]+3\left[(-1)^{1+3}\begin{vmatrix}2&3\\0&4\end{vmatrix}\right]

\Delta=3\left[-18\right]+0\left[(-1)(-4)\right]+3\left[8\right]

\Delta=-54+0+24

\Delta=-30

Therefore, the value of determinant is -30.

By cofactor expansion across the second column, we get

\Delta=a_{12}C_{12}+a_{22}C_{22}+a_{32}C_{32}

\Delta=0\left[(-1)^{2+1}\begin{vmatrix}2&3\\0&-2\end{vmatrix}\right]+3\left[(-1)^{2+2}\begin{vmatrix}3&3\\0&-2\end{vmatrix}\right]+4\left[(-1)^{3+2}\begin{vmatrix}3&3\\2&3\end{vmatrix}\right]

\Delta=0\left[(-1)(-4)\right]+3\left[(-6)\right]+4\left[(-1)3\right]

\Delta=-18-12

\Delta=-30

Therefore, the value of determinant is -30.
