Suppose I have to solve for y:
So I know that (x - 1) will always be 0 or a negative, therefore I must take the negative square root of (x - 1):
Am I to understand that this is the same as:
Or how does this work?
I don't really want to focus on solving the problem, I just need some insight on the negative square root operation.
I'm trying to understand the way it was done here:
Is this correct or incorrect?
