#### Explanation:

#"isolate "(x-2)^2" by subtracting 3 from both sides"#

#rArr(x-2)^2=4-3=1#

#color(blue)"take the square root of both sides"#

#sqrt((x-2)^2)=+-sqrt1larrcolor(blue)"note plus or minus"#

#rArrx-2=+-1#

#"add 2 to both sides"#

#rArrx=2+-1#

#rArrx=2-1" or "x=2+1#

#rArrx=1" or "x=3#
