Write matrix A sa

Answer :

Given:


To find: A


Let


Solving for matrix A, we get




Comparing the values, we get


a + 2 = 3 …(i)


b + 3 = -6 …(ii)


c – 1 = -3 …(iii)


and d + 4 = 8 …(iv)


Solving eq. (i), we get


a + 2 = 3


a = 1


Solving eq. (ii), we get


b + 3 = -6


b = -6 – 3


b = -9


Solving eq. (iii), we get


c – 1 = -3


c = -3 + 1


c = -2


Solving eq. (iv), we get


d + 4 = 8


d = 8 – 4


d = 4


Putting the value of a, b , c and d to get the matrix A, we get
