Step-by-step explanation:
Given that,
A= 4 9 & B= 2 1
-2 6 3 -2
equation is 3A-2B+2D=0
now, consider
3A= 3x4 9x3 =12 27
3x-2 6x3 -6 18
2B= 2x2 1x2 =4 2
3x2 -2x2 6 -4
now,3A-2B= 12-4 27-2 =8 25
-6-6 18+4 -12 22
3A-2B+2D=0 (given)
=> 8 25 +2D=0
-12 22
=>2D= -8 -25
+12 -22
=>D= -8/2 -25/2
12/2 -22/2
=>D= -4 -25/2
6 -11
therefore,
the matrix D= -4 -25/2
6 -11
