SUMMARY
The discussion centers on proving that the operator defined by L(A) = 2A is a linear operator. To establish linearity, one must demonstrate two properties: first, that L(A + B) = L(A) + L(B) for any n x n matrices A and B, and second, that L(cA) = cL(A) for any scalar c. Both conditions confirm that L is indeed a linear operator, adhering to the definition of linearity in matrix operations.
