    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'

    What you are maybe looking for is this:

    A XOR B = A'B + AB'
