Question Analysis
This question tests the student's ability to factor a multivariable polynomial by first extracting the greatest common factor (GCF) and then grouping the remaining terms.

Key Concept Explanation
Factoring by grouping involves identifying and extracting the GCF, and then grouping the remaining terms to find any common binomial factors.

Step-by-step Solution
1. Identify the GCF of all terms, which is :
2. Group the polynomial inside the parentheses:
3. Extract the GCF from the first group:
