Question 1 Report

Given matrix M = $| \begin{matrix} - 2 & 0 & 4 \\ 0 & - 1 & 6 \\ 5 & 6 & 3 \end{matrix} |$ , find $M^{T} + 2 M$

| \begin{matrix} - 4 & 2 & 1 \\ 6 & 0 & 5 \\ 0 & 6 & 2 \end{matrix} |

| \begin{matrix} - 6 & 0 & 13 \\ 0 & - 3 & 18 \\ 14 & 18 & 9 \end{matrix} |

| \begin{matrix} 5 & 2 & 6 \\ 0 & 1 & 1 \\ 3 & 4 & - 7 \end{matrix} |

| \begin{matrix} - 4 & 0 & 8 \\ 0 & - 2 & - 16 \\ 10 & 12 & 6 \end{matrix} |

Answer Details

M = $| \begin{matrix} - 2 & 0 & 4 \\ 0 & - 1 & 6 \\ 5 & 6 & 3 \end{matrix} |$
M $^{T}$ = $| \begin{matrix} - 2 & 0 & 5 \\ 0 & - 1 & 6 \\ 4 & 6 & 3 \end{matrix} |$
2M = $| \begin{matrix} - 4 & 0 & 8 \\ 0 & - 2 & 12 \\ 10 & 12 & 6 \end{matrix} |$
M $^{T}$ + 2M = $| \begin{matrix} - 6 & 0 & 13 \\ 0 & - 3 & 18 \\ 14 & 18 & 9 \end{matrix} |$
