Introduction
Algebraic expressions are a fundamental concept in mathematics, and simplifying them is an essential skill for any math enthusiast. In this article, we will explore the process of simplifying algebraic expressions, focusing on the specific example of the expression . We will break down the steps involved in simplifying this expression, using clear and concise language to ensure that readers of all levels can understand the process.
Step 1: Distribute 5 through the Parentheses
The first step in simplifying the expression is to distribute the 5 through the parentheses. This means that we need to multiply the 5 by each term inside the parentheses. To do this, we will use the distributive property, which states that for any numbers a, b, and c, the following equation holds:
a(b + c) = ab + ac
In our case, we have:
5(-2x - 6) = 5(-2x) + 5(-6)
Using the distributive property, we can rewrite this expression as:
5(-2x) - 5(6)
Step 2: Simplify the Expression
Now that we have distributed the 5 through the parentheses, we can simplify the expression further. To do this, we will multiply the 5 by each term inside the parentheses.
5(-2x) = -10x
5(-6) = -30
So, the simplified expression is:
-10x - 30

Introduction
Simplifying algebraic expressions is a crucial skill in mathematics, and it requires attention to detail and a clear understanding of the distributive property. In this article, we will answer some of the most frequently asked questions about simplifying algebraic expressions, providing clear and concise explanations to help readers develop a deeper understanding of this important concept.
Q&A
Q: What is the distributive property?
A: The distributive property is a mathematical concept that states that for any numbers a, b, and c, the following equation holds: a(b + c) = ab + ac. This means that we can distribute a single term to multiple terms inside the parentheses.
Q: How do I simplify an algebraic expression?
A: To simplify an algebraic expression, you need to follow these steps:
- Distribute: Distribute the terms inside the parentheses to each term outside the parentheses.
- Combine like terms: Combine any like terms that you have distributed.
- Check the expression: Check the expression for errors and make sure that it is simplified correctly.
Q: What are some common mistakes to avoid when simplifying algebraic expressions?
A: Some common mistakes to avoid when simplifying algebraic expressions include:
- Forgetting to distribute: Failing to distribute the terms inside the parentheses can lead to incorrect simplifications.
- Misusing the distributive property: Using the distributive property incorrectly can result in incorrect simplifications.
- Not checking the expression: Failing to check the expression for errors can lead to incorrect simplifications.
Q: How do I know if an expression is simplified?
A: An expression is simplified when there are no like terms that can be combined. In other words, if you have distributed all the terms and there are no like terms left, then the expression is simplified.
Q: Can I simplify an expression with variables?
A: Yes, you can simplify an expression with variables. The process is the same as simplifying an expression with numbers. You need to distribute the terms inside the parentheses and then combine like terms.
Q: What is the difference between simplifying and evaluating an expression?
A: Simplifying an expression means reducing it to its simplest form by combining like terms. Evaluating an expression means finding the value of the expression by substituting the values of the variables.
Q: How do I evaluate an expression?
A: To evaluate an expression, you need to substitute the values of the variables into the expression and then simplify it.
Q: Can I simplify an expression with fractions?
A: Yes, you can simplify an expression with fractions. The process is the same as simplifying an expression with numbers. You need to distribute the terms inside the parentheses and then combine like terms.
Q: What are some real-world applications of simplifying algebraic expressions?
A: Simplifying algebraic expressions has many real-world applications, including:
- Science: Simplifying expressions is used in science to model real-world phenomena and make predictions.
- Engineering: Simplifying expressions is used in engineering to design and optimize systems.
