Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Distributive Property
The distributive property states that a(b + c) = ab + ac. This property allows us to multiply a single term by each term within a set of parentheses, facilitating the simplification of expressions. In the given expression, applying the distributive property helps to eliminate the parentheses and combine like terms.

Combining Like Terms
Combining like terms involves adding or subtracting terms that have the same variable raised to the same power. This process simplifies expressions by consolidating similar components into a single term, making it easier to work with. In the expression provided, after applying the distributive property, combining like terms will lead to a more simplified result.
