\(\begin{pmatrix} -6 & 17 \\ 3 & 1 \end{pmatrix}\)
\(\begin{pmatrix} -2 & 9 \\ 4 & 1 \end{pmatrix}\)
\(\begin{pmatrix} 0 & -6 \\ 9 & -8 \end{pmatrix}\)
\(\begin{pmatrix} 0 & 10 \\ 9 & -4 \end{pmatrix}\)
Correct answer is D
\(P = \begin{pmatrix} 2 & 1 \\ 5 & -3 \end{pmatrix} ; Q = \begin{pmatrix} 4 & -8 \\ 1 & -2 \end{pmatrix}\)
\(2P = \begin{pmatrix} 4 & 2 \\ 10 & -6 \end{pmatrix}\)
\(2P - Q = \begin{pmatrix} 4 & 2 \\ 10 & -6 \end{pmatrix} - \begin{pmatrix} 4 & -8 \\ 1 & -2 \end{pmatrix}\)
= \(\begin{pmatrix} 0 & 10 \\ 9 & -4 \end{pmatrix}\)
