Answer:
both are square matrix of 2×2
equate corresponding elements and solve
3 = d or d = 3
5+c = -1 or c = -6
a+b = 6 and ab = 8 => a = 8/b
8/b + b = 6
=> 8 + b² = 6b
=> b² - 6b + 8 =0
=> b² -4b - 2b + 8 = 0
=> b(b-4)-2(b-4) = 0
=> (b-4)(b-2) = 0
=> b-4 = 0 or b = 4 and b - 2 = 0 or b = 2
therefore a= 4 or a = 2
a= 4 , b= 2 c = -6 d = 3
or
a= 2, b = 4, c = -6 d = 3
