Question
Identify the correct statement(s)
Options
A.If system of n simultaneous linear equations has a unique solution, then coefficient matrix is singular
B.If system of n simultaneous linear equations has a unique solution, then coefficient matrix is non singular
C.If A-1 exists, (adj A)-1 may or may not exist
D.F(x) = 
, then F(x) . F(y) = F(x - y)
, then F(x) . F(y) = F(x - y)Solution
