Thread: square root equation

I really don't get what I'm supposed to do with this problem. If someone could show me the steps, that would be great.

radical (x + 1) = x - 1

(that's supposed to be a radical sign over the x+1)

square both sides and solve for x. then check your solutions in the original equation to make sure none are extraneous
