This fundamental algebraic concept involves multiplying a single term by a sum or difference of terms within parentheses. For example, 3(x + 2) simplifies to 3x + 6 by multiplying both x and 2 by 3. This process is frequently coupled with the simplification of expressions by combining similar terms. This might involve adding or subtracting terms with the same variable and exponent, such as simplifying 3x + 2x + 6 to 5x + 6. Practice problems on worksheets reinforce these skills through repetitive application in varied scenarios.
Mastery of these combined skills forms a cornerstone of algebra, laying the groundwork for solving equations, factoring, and working with more complex mathematical concepts. By breaking down complex expressions into simpler forms, these processes streamline calculations and provide a more manageable approach to problem-solving. Historically, the development of these algebraic techniques has been crucial for advancements in various fields, from physics and engineering to computer science and economics.
