If , then the system of equation has non-trivial solution.
The given homogeneous system can be written in matrix form
So, the given system of equation has a non-trivial solution.
To find these solutions, we write the first two equations as
Let , then we have
Put in third equation, so these values satisfies it.
Hence ,, where
