Prove that: |0a-b-a0-c b c0|=0 ....

Prove that: `|0a-b-a0-c b c0|=0` .

Text Solution

Verified by Experts

The correct Answer is:
`Delta = 0`
We have, Applying `R_{\mathbf{1}} \rightarrow c R_{1}`, we have: $$ \Delta=\frac{1}{c}\left|\begin{array}{lll} 0 & a c & -b c \\ -a & 0 & -c \\ b & c & 0 \end{array}\right| ...
