Radical expression are expressions that contains square root. The value of x from the given radical expression is 3
<h3>Radical equations and expression</h3>
Given the equation expressed as:
x = 2 + √x - 2
Subtract 2 from both sides
x - 2 = √x - 2
Square both sides
(x-2)^2 = x - 2
x - 2 = 1
x = 1 + 2
x = 3
Hence the value of x from the given radical expression is 3
