Asked by Sam
I'm using the quadratic equation and I understand how to use it, but the format my text book gives the answers in is what I don't understand.
If I have (2+/-Sqrt(8))/2
I know that x can either equal 2.41 or -0.14
However, my textbook is giving me the answers as 1+Sqrt(2) and 1-Sqrt(2)
I understand where the 1+/- comes from, but how are they getting Sqrt(2)?
I hope you can understamd what I mean. I'm confised, so I wasn't sure how to word the question correctly, but I hope you can see where I am having trouble.
Thank you.

sqrt(8) can be simplified because 8 = 2^3
