If you are solving a quadratic equation and the directions say to "round to the nearest hundredth" or "leave your answer in simplest radical form", what does that tell you about the method that you should use to solve?

Generally, when dealing with "round to the nearest hundredth", you can just plug the numbers into a clac. 

So if my answer was sqrt(2), I'd just type that in a calc and get 1.4142135623 and round to 1.41. 

If it says "leave your answer in simplest radical form", just keep it as sqrt(2). 



To solve a quadratic, you can either use the quadratic formula, or you can factor if the number is nice. :))

There's a nice khan academy video on both of those topics.
