Hi all Thanks in advance for help! Trying to simplify: (x-a)^2 = b I believe the answer is x = a+b or a-b... can you please show working? Thanks!

If by simplify you mean solve for x then $\displaystyle \left ( x-a \right )^{2}=b$ Take the square root of both sides $\displaystyle x-a=\sqrt{b}$ Add a to both sides to give $\displaystyle x=\pm \sqrt{b}+a$
Which is close to your answer if you write it this way $\displaystyle x=a\pm \sqrt{b}$
Thanks!
