I just want to know how you decide whether to use the A-lambda method or by multiplying A by the vector (V1, V2) to get lambda(V1, V2) and then using substitution etc. when finding eigenvals/vecs. Thanks

I am not clear what the "A- lamba" method is or exactly what you are asking. I suspect you mean solving. If so then, yes, that is the simplest way to find eigenvalues for reasonable sized matrices. For very large matrices there are various numerical methods that can be used on computers.
