    i get the answer -1/8

    First start with factorizing a²+2ab+b² = (a+b)² and 8a+8b is 8(a+b)

    (a+b)²/8(a+b) * b-a/a²-b² and simplify

    (a+b)/8 * b-a/a²-b²

    next b-a = -(a-b) and a²-b² = (a+b)(a-b)

    (a+b)/8 * -(a-b)/(a+b)(a-b) and now simplify

    -(a+b)/8 * 1/(a+b)

    -1/8

    [(a+b)^2] / 8 (a+b) * 0 is the answer i think
