Question Analysis
This problem tests the ability to simplify a radical expression by factoring the radicand and applying the properties of radicals.

Key Concept Explanation
To simplify , we need to factor the radicand into a product of a perfect square and another factor. The property is used to separate the perfect square part from the remaining factor.

Step-by-step Solution
1. Factor the radicand: , where .
2. Separate the perfect square part:
