What is the result of applying R2←R2−R1R_2 \leftarrow R_2 - R_1R2←R2−R1 to the matrix (2325)\begin{pmatrix} 2 & 3 \\ 2 & 5 \end{pmatrix}(2235)?
(2302)\begin{pmatrix} 2 & 3 \\ 0 & 2 \end{pmatrix}(2032)
(0225)\begin{pmatrix} 0 & 2 \\ 2 & 5 \end{pmatrix}(0225)
(2312)\begin{pmatrix} 2 & 3 \\ 1 & 2 \end{pmatrix}(2132)
(0−225)\begin{pmatrix} 0 & -2 \\ 2 & 5 \end{pmatrix}(02−25)
