Introduction

Simplifying algebraic expressions is a crucial skill in mathematics, and it's essential to understand the rules and techniques involved. In this article, we will focus on simplifying the expression 8x2(x+3)8x - 2(x + 3) using the distributive property and combining like terms.

Understanding the Distributive Property

The distributive property is a fundamental concept in algebra that allows us to expand expressions by multiplying each term inside the parentheses with the term outside. In the given expression, we have 8x2(x+3)8x - 2(x + 3), and we need to apply the distributive property to simplify it.

Applying the Distributive Property

To simplify the expression, we will apply the distributive property by multiplying each term inside the parentheses with the term outside. This means we will multiply 8x8x with 2-2 and 33 with 2-2.

8x - 2(x + 3) = 8x - 2x - 6

Combining Like Terms

Now that we have expanded the expression, we can combine like terms to simplify it further. Like terms are terms that have the same variable raised to the same power. In this case, we have 8x8x and 2x-2x, which are like terms.

8x - 2x = 6x

Simplifying the Expression

Now that we have combined like terms, we can simplify the expression by subtracting 66 from the result.

6x - 6

Conclusion

In conclusion, the simplified form of the expression 8x2(x+3)8x - 2(x + 3) is 6x66x - 6. This is the correct answer among the options provided.

Answer Options

Here are the answer options:

  • A. 6x+66x + 6
  • B. 6x+36x + 3

Introduction

In our previous article, we discussed how to simplify the expression 8x2(x+3)8x - 2(x + 3) using the distributive property and combining like terms. In this article, we will answer some frequently asked questions (FAQs) related to simplifying expressions.

Q: What is the distributive property?

A: The distributive property is a fundamental concept in algebra that allows us to expand expressions by multiplying each term inside the parentheses with the term outside. For example, in the expression 8x2(x+3)8x - 2(x + 3), we can apply the distributive property to get 8x2x68x - 2x - 6.

Q: How do I know which terms to combine?

A: To combine like terms, you need to identify the terms that have the same variable raised to the same power. In the expression 8x2x8x - 2x, we can combine the terms because they both have the variable xx raised to the power of 1.

Q: What is the difference between like terms and unlike terms?

A: Like terms are terms that have the same variable raised to the same power. Unlike terms are terms that have different variables or different powers of the same variable. For example, in the expression 8x2y8x - 2y, 8x8x and 2y2y are unlike terms because they have different variables.

Q: Can I simplify expressions with fractions?

A: Yes, you can simplify expressions with fractions by applying the distributive property and combining like terms. For example, in the expression 12x13(x+2)\frac{1}{2}x - \frac{1}{3}(x + 2), you can apply the distributive property to get 12x13x23\frac{1}{2}x - \frac{1}{3}x - \frac{2}{3}.

Q: How do I simplify expressions with exponents?

A: To simplify expressions with exponents, you need to apply the rules of exponents. For example, in the expression 23222^3 \cdot 2^2, you can simplify it by adding the exponents to get 252^5.

Q: Can I simplify expressions with variables in the denominator?

A: Yes, you can simplify expressions with variables in the denominator by applying the rules of fractions. For example, in the expression x2x3\frac{x}{2} - \frac{x}{3}, you can simplify it by finding a common denominator to get 3x2x6\frac{3x - 2x}{6}.

Q: How do I check my work when simplifying expressions?

A: To check your work, you can plug in values or use a calculator to evaluate the expression. For example, if you simplify the expression 8x2(x+3)8x - 2(x + 3) to get 6x66x - 6, you can plug in a value for xx to check if the expression is true.
