Introduction

In mathematics, simplifying expressions is an essential skill that helps us to solve problems more efficiently and accurately. In this article, we will focus on simplifying the expression 4n+126\frac{4n + 12}{6}. We will break down the steps involved in simplifying this expression and provide a clear explanation of each step.

Understanding the Expression

The given expression is 4n+126\frac{4n + 12}{6}. To simplify this expression, we need to understand the concept of simplifying fractions. A fraction is a way of representing a part of a whole. In this case, the fraction 4n+126\frac{4n + 12}{6} represents a part of the whole number 6.

Step 1: Factor Out the Greatest Common Factor (GCF)

The first step in simplifying the expression is to factor out the greatest common factor (GCF) of the numerator and the denominator. The GCF of 4n + 12 and 6 is 2. We can factor out 2 from both the numerator and the denominator.

4n+126=2(2n+6)2(3)\frac{4n + 12}{6} = \frac{2(2n + 6)}{2(3)}

Step 2: Cancel Out the Common Factors

Now that we have factored out the GCF, we can cancel out the common factors between the numerator and the denominator. In this case, we can cancel out the 2 in the numerator and the denominator.

2(2n+6)2(3)=2n+63\frac{2(2n + 6)}{2(3)} = \frac{2n + 6}{3}

Step 3: Simplify the Expression

Now that we have cancelled out the common factors, we can simplify the expression further. We can see that the expression 2n+63\frac{2n + 6}{3} is already in its simplest form.

Conclusion

In conclusion, simplifying the expression 4n+126\frac{4n + 12}{6} involves factoring out the greatest common factor (GCF) and cancelling out the common factors between the numerator and the denominator. By following these steps, we can simplify the expression and arrive at its simplest form.

Introduction

In our previous article, we discussed how to simplify the expression 4n+126\frac{4n + 12}{6}. In this article, we will provide a Q&A guide to help you understand the concept of simplifying expressions and answer any questions you may have.

Q: What is the greatest common factor (GCF)?

A: The greatest common factor (GCF) is the largest number that divides both the numerator and the denominator of a fraction. In the expression 4n+126\frac{4n + 12}{6}, the GCF is 2.

Q: How do I find the GCF of two numbers?

A: To find the GCF of two numbers, you can list the factors of each number and find the largest factor they have in common. For example, the factors of 4n + 12 are 1, 2, 3, 4, 6, 12, and the factors of 6 are 1, 2, 3, 6. The largest factor they have in common is 2.

Q: What is the difference between factoring and simplifying?

A: Factoring and simplifying are two related but distinct concepts. Factoring involves breaking down an expression into its component parts, while simplifying involves reducing an expression to its simplest form by cancelling out common factors.

Q: How do I simplify an expression with variables?

A: To simplify an expression with variables, you can follow the same steps as simplifying an expression with numbers. First, factor out the GCF, then cancel out the common factors between the numerator and the denominator.

Q: What is the importance of simplifying expressions?

A: Simplifying expressions is an essential skill in mathematics that has many real-world applications. By simplifying expressions, you can solve problems more efficiently and accurately, and make complex calculations easier to understand.

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

A: To check your work when simplifying expressions, you can plug in values for the variables and see if the expression simplifies to the expected result. For example, if you simplify the expression 4n+126\frac{4n + 12}{6} to 2n+63\frac{2n + 6}{3}, you can plug in a value for n, such as n = 1, and see if the expression simplifies to the expected result.

Q: What are some common mistakes to avoid when simplifying expressions?

A: Some common mistakes to avoid when simplifying expressions include:

  • Not factoring out the greatest common factor (GCF) between the numerator and the denominator.
  • Not cancelling out the common factors between the numerator and the denominator.
