    Answer:

    x = a² + b²

    y = a² – b²

    xy = ?

    = (a² + b²) (a² – b²)

    = a⁴ + a²b² + b²a² – b⁴

    = a⁴ + a²b² – a²b² – b⁴

    = a⁴ – b⁴

    Answer:

    a^4 – b^4

    Step-by-step explanation:

    x = a^2 + b^2

    y = a^2 – b^2

    xy = (a^2 + b^2)(a^2 – b^2)

    xy = a^4 + (a^2 b^2) – (a^2 b^2) – b^4

    xy = a^4 – b^4
