Siobhan performs the elementary row operation represented by 2R3-R2 on matrix A.

Answer:
The matrix would be:
-1 2
12 2
6 3
-3 -4
Step-by-step explanation:
Took the quiz.
The matrix representation that results from the transformation will be:
[tex]\left[\begin{array}{ccc}-1&2\\0&4\\12&2\\-3&-4\end{array}\right][/tex]
Given the elementary matrix
[tex]\left[\begin{array}{ccc}-1&2\\0&4\\6&3\\-3&-4\end{array}\right][/tex]
The question required us to transform the matrix by using the elementary row operator 2R₃-R₂
Applying the transformation will create a new Row 3 as shown below:
The equivalent matrix will be:
[tex]\left[\begin{array}{ccc}-1&2\\0&4\\12&2\\-3&-4\end{array}\right][/tex]
