    Answer:

    4[(a- 4)(a+4)]

    Step-by-step explanation:

    4a^2 – 64

    From the above, 4 is a common factor. The expression can be written as:

    4[a^2 – 16]

    16 can be written as 4^2

    4[a^2 – 4^2]

    Now, we have difference of two squares. This is written as:

    4[(a- 4)(a+4)]
