Question Analysis
This question tests the ability to factor a multivariable polynomial with negative coefficients, focusing on extracting common factors and grouping.

Key Concept Explanation
To factor such polynomials, first identify and extract any common factors, then group terms appropriately to find further common factors.

Step-by-step Solution
1. Step 1: Group the terms into two pairs
Group the first two terms and the last two terms:
2. Step 2: Factor out the GCF from each group
From the first group , the GCF is :
From the second group , the GCF is 3:
