I was supposed to factor $\displaystyle 16p^2-64$, and following the steps I ended up with $\displaystyle 8(2p^2-8)$ I don't think that's factored COMPLETELY though?

Then I was supposed to factor $\displaystyle 4n^2-32n+48$ , and I got $\displaystyle 4(n^2-8n+12)$ . I don't think that's factored completely either?! Were there different steps I was supposed to follow or something?

your input would be greatly appreciated!

thanks!
