Set of numbers containing square roots
I am having trouble with this file: I am trying to express the solutions of an equation as a set of numbers, where square roots should keep their algebraic expression (not as a decimal).
I tried it with the SurdText-command, but I don't seem to get it right.
I tried three different solutions (all yellow text-boxes at the end of the file).
Do you have an advice for me?
Thank you in advance!
