Quizplus · Accepted Answer

The given expression cannot be directly solved by extracting square roots as it is not an equation. However, the correct choice involves completing the square, which leads to $\left( x + \frac { 1 } { 3 } \right) ^ { 2 }$, indicating a misunderstanding in the question's formulation.
