Sorry, but your matrices do not make sense.If you multiply a matrix by a scalar the resulting (product) matrix has exactly the same structure as the one you multiplied : (mXn) times a yields another (mXn) matrix.
Be it as it may, when you multiply a matrix by a scalar, you obtain the product by multiplying every element of the original matrix by the scalar.
Here is a screen capture showing the multiplication of a 2X2 matrix by a scalar.
Note: I have noticed that screen captures I insert in my answers are sometimes deleted (by FixYa?). So if you do not see a picture it has nothing to do with me.

Hello,
The so-called (2x1) matrix is not a matrix. It is a vector.
Hope it helps.

Having gone over a month with no response, I assume this is no longer a problem.

Matrix multiplication is defined only when the width of the first matrix is equal to the height of the second. You can multiply a 2x2 matrix by a 1x2 matrix or multiply a 2x1 matrix by a 2x2 matrix, but you cannot multiply a 2x2 matrix by a 2x1 matrix.
