This is a question that appeared in my mid-semester test and I would like someone to explain it to me. Thanks in advance.
Given that the matrices A, B and X are m x m order and (I_m) is the identity matrix.
Solve for matrix X, the equation:
AX - BA = (I_m)
Edit: Matrix A, B and X are of m x m order
It has been some time since I did engineering maths, I am quite rusty.
None of the matrices are given
It is given to me that they are of m x m order but they are not given,
Yes this is a very general question but it is in my Mid Sem exam in EEE diploma
And thank you so much !
That was the solution that I was looking for !
I guess the question wants to test the student's knowledge on manipulating matrix equations, and wants the students to know that a matrix cannot be "divided", and have to use the inverse property.
I have added in some more details and fit the document into a single page pdf file and it can be downloaded here
In case you specialise in power Engineering in SP EEE, I wrote a solution for one of the past year questions recently.
Verify with your lecturer on the accuracy of my solutions, hopefully my approach fits his requirements.
I also believe that this task is aimed at testing knowledge on the manipulation of matrix equations. To solve matrix, I sometimes use the Wolfram Alpha application or website https://assignment.essayshark.com/math-help.html to get a more detailed explanation of a particular action in a real example, or just check the validity of my solutions.
Interesting kind of solution...

Then as and when you encounter difficulty when doing the questions, you make a mark on those questions and ask your lecturer for help during the tutorial session.
