Simplify The Expression, If Possible:\[$-4r + 8R + 2R - 6r + R\$\]

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 focus on simplifying a given algebraic expression, which involves combining like terms and applying the rules of arithmetic operations. Our goal is to simplify the expression, if possible, and provide a clear understanding of the steps involved.

The Given Expression

The given expression is:

$$-4r + 8R + 2R - 6r + R$$

Step 1: Identify Like Terms

To simplify the expression, we need to identify like terms, which are terms that have the same variable raised to the same power. In this case, we have two like terms: $-4r$ and $-6r$, which both have the variable $r$ raised to the power of 1.

Step 2: Combine Like Terms

Now that we have identified the like terms, we can combine them by adding or subtracting their coefficients. In this case, we have:

$$-4r + (-6r) = -10r$$

So, the expression becomes:

$$-10r + 8R + 2R + R$$

Step 3: Simplify the Expression

Now that we have combined the like terms, we can simplify the expression further by combining the remaining terms. We have two like terms: $8R$ and $2R$, which both have the variable $R$ raised to the power of 1.

$$8R + 2R = 10R$$

So, the expression becomes:

$$-10r + 10R + R$$

Step 4: Final Simplification

Now that we have combined the remaining terms, we can simplify the expression further by combining the like terms. We have two like terms: $10R$ and $R$, which both have the variable $R$ raised to the power of 1.

$$10R + R = 11R$$

So, the final simplified expression is:

$$-10r + 11R$$

Conclusion

In this article, we have simplified the given algebraic expression by combining like terms and applying the rules of arithmetic operations. We have shown that the expression can be simplified to:

$$-10r + 11R$$

This simplified expression is a result of careful analysis and application of mathematical rules. We hope that this article has provided a clear understanding of the steps involved in simplifying algebraic expressions.

Final Thoughts

Introduction

In our previous article, we explored the process of simplifying algebraic expressions by combining like terms and applying the rules of arithmetic operations. In this article, we will provide a Q&A guide to help you better understand the concepts and techniques involved in simplifying algebraic expressions.

Q1: What are like terms?

A: Like terms are terms that have the same variable raised to the same power. For example, $2x$ and $5x$ are like terms because they both have the variable $x$ raised to the power of 1.

Q2: How do I identify like terms?

A: To identify like terms, look for terms that have the same variable raised to the same power. You can also use the distributive property to rewrite terms and make it easier to identify like terms.

Q3: What is the distributive property?

A: The distributive property is a mathematical rule that states that a single term can be distributed to multiple terms. For example, $3(2x + 5)$ can be rewritten as $6x + 15$ using the distributive property.

Q4: How do I combine like terms?

A: To combine like terms, add or subtract their coefficients. For example, $2x + 5x$ can be combined to get $7x$.

Q5: What are the rules of arithmetic operations?

A: The rules of arithmetic operations are the basic rules that govern how numbers and variables are combined. The rules include:

• The commutative property: $a + b = b + a$
• The associative property: $(a + b) + c = a + (b + c)$
• The distributive property: $a(b + c) = ab + ac$
• The order of operations: Evaluate expressions in the following order: parentheses, exponents, multiplication and division, and addition and subtraction.
