all those words! How about
4√(x-2)+4=2
18 is not in the domain, nor is any other real number, because √ is positive. There's no way to add a positive value to 4 and end up with 2.
Is x=18 in the solution set of the radical equation 4 root of x minus 2 end root plus 4 equals 2 ? Tell why or why not.
