Question

Find the given elements of matrix D :

D=
-2 -4 2 - -2 -2 -2
0 6 4 4 4 4
d₁₁=-2
d₁₂= -1
d₁₃= 4
d₂₁=2
d₂₂= -10
d₂₃= -2

Answer 1

Explanation:

`D=\left[\begin{array}{ccc}-2&-4&2\\0&6&4\\\end{array}\right] -\left[\begin{array}{ccc}-2&-2&-2\\4&4&4\\\end{array}\right] \\\\\\D=\left[\begin{array}{ccc}(-2-(-2))&(-4-(-2))&(2-(-2))\\(0-4)&(6-4)&(4-4)\\\end{array}\right] \\\\\\D=\left[\begin{array}{ccc}(-2+2)&(-4+2)&(2+2)\\-4&2&0\\\end{array}\right] \\\\\\D=\left[\begin{array}{ccc}0&-2&4\\-4&2&0\\\end{array}\right] \\\\\\d_(11)=0\ \ \ \ d_(12)=-2\ \ \ \ d_(13)=4\\\\d_(21)=-4\ \ \ \ d_(22)=2\ \ \ \ d_(23)=0`
