Answer:

#x^2 + 16x + 64#

Explanation:

You can use the formula for the square of a binomial:

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

So, the square of a sum consists in the square of the first term, plus the square of the second, plus twice the product of the two terms. In your case,

#(x+8)^2 = x^2 + 16x + 64#.
