    Answer:since

    a²+b²=(a+b)²-2ab,


    then


    a²+b²=12²-2×14,


    a²-b²=144-28,


    a²-b²=116

    Hope it will helps you!!!

    Let a2+b2 be x

    (a + b) whole square = a square + 2ab + B square

    12 square. = a square + B square + 14 x2

    144. = x + 28

    144-28. = x

    116. = x
