Radical Equation with Solution:
Since this equation is in the form "(square root) = (number)", I can proceed directly to squaring both sides:
       x – 2 = 25
            x = 27
This solution matches what I would expect from the graph of the two sides of the equation: As you can see above, the lines:
y = 5
...intersect at x = 27, as the algebra had already shown me. Checking, I get:So the solution is x = 27.
