Final answer:
The expression s²+16s+64 can be factored as (s+8)(s+8).
Step-by-step explanation:
The expression s²+16s+64 can be factored as (s+8)(s+8).
Here's how:
- Notice that the last term, 64, is a perfect square.
- Identify the factors of the perfect square that add up to the middle term, 16:
8 and 8. - Write the factors in parentheses, with the same sign as the middle term:
(s+8)(s+8).
