I want to reduce this expression - AB' + BA'

The steps I followed are below, can you please check if it is correct ?

>> A [ B' + B (A'/A)]
>> A [ (A'/A) + B]
>> A' + AB // ( X + X'Y) = X + Y (using formulas from text)

>> A' + B // so let X = A'

 

>> A [ B' + B (A'/A)]

i seriously doubt u can do that above process. check this link:

IMO, u can't reduce ur given expression further.

 

hmm, thank you.

 

What you are maybe looking for is this:

A XOR B = A'B + AB'
