    Step-by-step explanation:

    (a+b) ^2

    This is the product of squares and equals

    (a+b) (a+b) = a^2 + 2ab + b^2

    Rearranging the terms

    a^2 + b^2 + 2*ab

    We know a^2+b^2 = 16 and ab = 9

    16 + 2 (8)

    16+16

    Step-by-step explanation:

    (a + b) ² = a² + 2ab + b²

    = (a² + b²) + 2 (ab)

    = 16 + 2 (8)

    = 32
