(adsbygoogle = window.adsbygoogle || []).push({}); reducing sqrt(4t^2+4+1/t^2) to (1+2t^2)/t

3. The attempt at a solution

- This is actually just a portion of a calculus problem, but I can't figure out how the book did the algebra here. I get (2t^2+2t+1)/t and don't know how that reduces to (1+2t^2)/t. Please help.
