Best ResponseYou've already chosen the best response.2But I am not sure. The right hand side x will always be negative. The left hand side will be positive unless we are recognizing the negative root (which I am willing to do).

Best ResponseYou've already chosen the best response.2Lets do a trial. Let x=1, then \[\sqrt{((1))^{2}}=x\]\[\pm1=1\] I guess this is not totally true. Forget d

Best ResponseYou've already chosen the best response.2Yes I see it, the double negative when a x<0 was substituted on the left was confusing me.

Best ResponseYou've already chosen the best response.2The fact that the total was being squared, then the square root was to be taken. The right hand side was straight forward for me. Thank goodness, I have passed the test taking phase of my life lol.

Best ResponseYou've already chosen the best response.1lol This is the way I looked at it \[\sqrt{(x)^2}=x=1x=1x=x\]

Best ResponseYou've already chosen the best response.2Yes that makes it most obvious to the casual observer (like me)
