    Answer:

    x^2 – 64

    Step-by-step explanation:

    A difference of squares is a special product in the form (a^2 – b^2)..their factored form is (a – b)(a + b)..

    Thus here a = x and b = 8, thus if x + 8 is a factor, then x – 8 is also a factor..

    (x + 8)(x – 8) <– expand this out using difference of squares rules..

    = (x)^2 – (8)^2 

    = x^2 – 64 <– answer…

    You could also expand that using FOIL (FOIL – first, outer, inner, last)..

    (x + 8)(x – 8) 

    = (x)(x) + (x)(-8) + (8)(x) + (8)(-8) 

    = x^2 – 8x + 8x – 64 <– the -8x and 8x cancels out..leaving you with..

    = x^2 – 64
