Understanding the Problem

The given problem involves simplifying an algebraic expression using the distributive property and combining like terms. The expression to be simplified is 4(3x−2)+6x(2−1)4(3x - 2) + 6x(2 - 1). Our goal is to simplify this expression and choose the correct answer from the options provided.

Step 1: Apply the Distributive Property

To simplify the given expression, we need to apply the distributive property, which states that for any real numbers aa, bb, and cc, a(b+c)=ab+aca(b + c) = ab + ac. We can apply this property to both terms in the expression.

4(3x - 2) + 6x(2 - 1) = 4(3x) - 4(2) + 6x(2) - 6x(1)

Step 2: Simplify Each Term

Now, we can simplify each term by multiplying the numbers outside the parentheses with the terms inside.

4(3x) - 4(2) + 6x(2) - 6x(1) = 12x - 8 + 12x - 6x

Step 3: Combine Like Terms

The next step is to combine like terms, which involves adding or subtracting terms that have the same variable and exponent. In this case, we can combine the terms with the variable xx.

12x - 8 + 12x - 6x = 18x - 8

Conclusion

After simplifying the given expression using the distributive property and combining like terms, we arrive at the simplified expression 18x−818x - 8. This expression matches option A, which is the correct answer.

Answer

The simplified expression for the given algebraic expression is 18x−818x - 8. Therefore, the correct answer is:

A. 18x−818x - 8

Why is this the Correct Answer?

The correct answer is 18x−818x - 8 because it is the result of simplifying the given expression using the distributive property and combining like terms. This answer is obtained by applying the rules of algebra and simplifying the expression step by step.

Conclusion

Q: What is the distributive property, and how is it used in simplifying algebraic expressions?

A: The distributive property is a fundamental concept in algebra that states that for any real numbers aa, bb, and cc, a(b+c)=ab+aca(b + c) = ab + ac. This property is used to simplify expressions by distributing numbers outside the parentheses to the terms inside.

Q: How do I apply the distributive property to simplify an algebraic expression?

A: To apply the distributive property, simply multiply the numbers outside the parentheses to the terms inside. For example, if you have the expression 4(3x−2)4(3x - 2), you would multiply 4 to both terms inside the parentheses, resulting in 12x−812x - 8.

Q: What is the difference between combining like terms and simplifying an algebraic expression?

A: Combining like terms involves adding or subtracting terms that have the same variable and exponent. Simplifying an algebraic expression, on the other hand, involves using the distributive property and combining like terms to reduce the complexity of the expression.

Q: How do I know which terms to combine when simplifying an algebraic expression?

A: To determine which terms to combine, look for terms that have the same variable and exponent. For example, if you have the expression 12x+6x12x + 6x, you can combine the two terms by adding their coefficients, resulting in 18x18x.

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 numbers outside the parentheses to the terms inside.
  • Not combining like terms.
  • Making arithmetic errors when performing operations such as addition, subtraction, multiplication, and division.

Q: How can I check my work when simplifying an algebraic expression?

A: To check your work, simply re-evaluate the expression using the distributive property and combining like terms. You can also use a calculator or a computer algebra system to verify your answer.
