to factor (x2-16x+64), you need to find two number whose product is 64 and whose sum is 16.

These two numbers are 8 and 8.

(x2-16x+64)=(x-8)(x-8)

You factor the equation by determining what two numbers, when added, equal 16 and, when multiplied, equal 64. For this equation, the two numbers are 8 and 8. (x+8)*(x+8)=x2+16x+64.
