@xapproachesinfinity the answer is one but can you tell me how to solve it? Do you square it or just add 1 to both sides??

xapproachesinfinity · Answer

you need to square root both sides$ \sqrt{x-1}=0 ====>(\sqrt{x-1})^2=0^2==>x-1=0$

anonymous · Answer

look first you square both sides to get (x-1 = 0)
then add 1 to both sides to get (x=1
