Okay. Use equation. They're telling us to find each of exit H of X is minus slow. So I put a minus 12 year and you see right away I can cancel this three this file submit. This becomes four. So now the equation is X minus four. Swear pickle. Two months. Yes. Okay, so now get a square root of each side. Get X minus four is speak well to plus minus and minus one becomes I four becomes 22 becomes too. I right and X is equal to four plus minus two I with many of these very straightforward. But when you have to know is if I have minus four, I really have a minus one and it four. And if you get a square root of this, what happens? You have I It's a sign and four becomes too. So this is saying is to I think a little extra explanation again, but check. Thank you.
