Weird square root disappearing and flipping fraction upside down?
So here I was, making 2 math problems, I was able to solve them, but 2 operations seem a bit intractable to me. Maybe you can help me understand why this is true:
The first problem:
Why is it possible to turn upside down?
The second problem:
Where does the -√B go? I understand that the -1 comes from the - sign in front of the square root. But where does the other √B go?
Everything, except above the bold text I understand. Maybe I do not understand the full extent of a certain rule which I am familiar with in simpler situations. That's why I think an example would be very useful. I really want to have a deep understand of why these things are true.
