$(s + 10) (s + 2)$ $(s+10)(s+2)$

Let's do a little thought experiment:

What two numbers sum up to the middle term, and have a product of the last term?

After some trial and error, we arrive at $10$ $10$ and $2$ $2$ . Because of this, we can factor our quadratic as

$(s + 10) (s + 2)$ $(s+10)(s+2)$

Hope this helps!
