If your question is (sqrt x-2)= 1, then (sqrt x-2)^2 = 1^2 [meaning, square both sides to get rid of the square root]. You’ll get x - 2 = 1; add 2 to both sides, and you get x = 3.
If your question is (sqrt x) - 2 = 1 [meaning, the -2 is not included in the radical sighn], then add 2 to both sides, and you get (sqrt x) = 3. Square both sides, and you get x = 9.

Let's see now...
sqrt x-2=1, therefore sqrt x=3 by adding 2 to both sides,
therefore x=9, by squaring both sides.
easy, huh?

sqrt x - 2 = 1
sqrt x - 2 = sqrt 1
x - 2 = 1
x = 2 + 1
x = 3 or sqrt x = 9

1) sqrtx - 2=1
sqrtx = 3
x=9.
2) sqrt(x-2) = 1
x-2 = 1
x= 3.

If sqrt(x)-2=1
sqrt(x)=3
x=9
If sqrt(x-2)=1
x-2=1
x=3
not sure which it was because of parenthesis

sqrt(x - 2) = 1
square both sides
x - 2 = 1
x = 3
ANS : x = 3

squarroot of x-2=1 .. square both sides so x=3.

â(x-2)=1 square both sides
x-2=1 add 2 to each side
x=3
