Question Analysis
This question tests the ability to simplify a polynomial expression and identify the coefficient of a specific term. It aligns with the concept of coefficients in polynomials and requires understanding of combining like terms.

Key Concept Explanation
To find the coefficient of a term after simplifying an expression, first distribute and combine like terms. The coefficient is the numerical factor (including its sign) that multiplies the variable part.

Step-by-step Solution
1. Start with the expression:
2. Distribute the 2 inside the parentheses:
