Well, since we are talking about a second-degree equation, we should at least check if there might be another root (it could be the same). The equation is:
x + x^2 = 2
iff x^2 + x - 2 = 0
iff (x+1/2)^2 - 2 - 1/4 = 0
iff (x+1/2)^2 = (3/2)^2
iff x+1/2 = +- 3/2
iff x = -2 or x = 1
Hence, the other solution is -2. Note that -2 + (-2)^2 = -2 + 4 = 2 as required.

What is the smallest three digit square number that is the sum of two squares?
The smallest three-digit square number is 100, which is (10^2). However, it cannot be expressed as the sum of two squares. The next three-digit square is 121 ((11^2)), which can be expressed as (11^2 = 10^2 + 1^2). Thus, 121 is the smallest three-digit square number that is also the sum of two squares.
