Breaking Down the Expression: $\frac{26ac^2}{13a}$

Let's focus on the expression $\frac{26ac^2}{13a}$ . This expression is a fraction, where the numerator is $26ac^2$ and the denominator is $13a$ . Our goal is to simplify this fraction by identifying and canceling common factors between the numerator and the denominator. This involves breaking down the coefficients and variables into their prime factors and then systematically eliminating any shared factors. By doing so, we can reduce the expression to its simplest form, making it easier to understand and work with.

To begin the simplification process, we first need to identify the common factors in the numerator and the denominator. The numerator, $26ac^2$ , consists of the coefficient 26 and the variables $a$ and $c^2$ . The denominator, $13a$ , consists of the coefficient 13 and the variable $a$ . We can see that both the numerator and the denominator share the factor $a$ . Additionally, the coefficients 26 and 13 share a common factor of 13. By recognizing these common factors, we can begin the process of canceling them out to simplify the expression.

The key to simplifying algebraic fractions lies in identifying and canceling common factors. A factor is a number or variable that divides evenly into another number or expression. For example, the factors of 26 are 1, 2, 13, and 26. The factors of $ac^2$ are $a$ , $c$ , and $c^2$ . By breaking down the numerator and denominator into their factors, we can easily identify the common ones and cancel them out. This process is similar to simplifying numerical fractions, where we divide both the numerator and denominator by their greatest common factor.

Step-by-Step Simplification

Now, let's walk through the step-by-step simplification of the expression $\frac{26ac^2}{13a}$ . This will provide a clear and concise method for tackling similar problems in the future. By breaking down the process into manageable steps, we can avoid errors and ensure that we arrive at the correct simplified expression. Each step builds upon the previous one, leading us closer to the final answer.

Factorize the coefficients:

The coefficient in the numerator is 26, which can be factored as $2 imes 13$ .
The coefficient in the denominator is 13.
So, we can rewrite the expression as $\frac{2 imes 13 imes a imes c^2}{13 imes a}$ .

Identify common factors:

Both the numerator and the denominator have a factor of 13.
Both the numerator and the denominator also have a factor of $a$ .

Cancel the common factors:

Divide both the numerator and the denominator by 13.
Divide both the numerator and the denominator by $a$ .
This leaves us with $\frac{2 imes c^2}{1}$ .

Simplify the expression:

The simplified expression is $2c^2$ .

By following these steps, we have successfully simplified the algebraic expression $\frac{26ac^2}{13a}$ to its simplest form, which is $2c^2$ . This process highlights the importance of factoring, identifying common factors, and systematically canceling them to achieve simplification. Remember to always double-check your work to ensure that you have canceled all common factors and that the final expression is indeed in its simplest form.

Key Concepts and Techniques

To master the simplification of algebraic expressions, it is essential to understand the underlying concepts and techniques. These include the rules of exponents, the properties of fractions, and the distributive property. By having a solid grasp of these concepts, you will be able to tackle a wide range of simplification problems with confidence and accuracy.

Rules of Exponents: The rules of exponents are crucial for simplifying expressions involving powers. For example, $x^m imes x^n = x^{m+n}$ and $\frac{x^m}{x^n} = x^{m-n}$ . In our example, we used the rule $\frac{a}{a} = a^{1-1} = a^0 = 1$ . Understanding and applying these rules correctly is essential for simplifying algebraic expressions involving variables raised to various powers.
Properties of Fractions: The properties of fractions are fundamental to simplifying algebraic fractions. We used the property that $\frac{ac}{bc} = \frac{a}{b}$ by canceling the common factor $c$ . This property allows us to reduce fractions to their simplest form by dividing both the numerator and denominator by their greatest common factor. A strong understanding of fraction properties is crucial for simplifying algebraic expressions involving fractions.
Distributive Property: The distributive property states that $a(b + c) = ab + ac$ . While we didn't directly use the distributive property in this specific example, it is a fundamental concept for simplifying more complex algebraic expressions. This property allows us to expand expressions and combine like terms, which is often a necessary step in the simplification process. Mastering the distributive property is essential for tackling a wide range of algebraic simplification problems.

Common Mistakes to Avoid

While simplifying algebraic expressions, it is easy to make common mistakes if you are not careful. Being aware of these potential pitfalls can help you avoid them and ensure that you arrive at the correct simplified expression. Some common mistakes include:

Incorrectly Canceling Terms: Only factors can be canceled, not terms. For example, in the expression $\frac{26ac^2}{13a}$ , we can cancel the factor $a$ because it is multiplied by other terms. However, we cannot cancel terms that are added or subtracted. Misunderstanding this distinction can lead to incorrect simplification.
Forgetting to Factor Completely: Before canceling common factors, make sure you have factored the numerator and denominator completely. This ensures that you identify all common factors and simplify the expression as much as possible. Failing to factor completely can result in a partially simplified expression.
Incorrectly Applying Exponent Rules: Make sure you apply the exponent rules correctly. For example, $\frac{x^m}{x^n} = x^{m-n}$ , not $x^{\frac{m}{n}}$ . Incorrect application of exponent rules can lead to errors in simplification.
Not Simplifying Completely: Always ensure that your final expression is in its simplest form. This means that there are no more common factors to cancel and that all like terms have been combined. A partially simplified expression is not the final answer.

Practice Problems

To solidify your understanding of simplifying algebraic expressions, it is essential to practice. Here are a few practice problems that you can try:

$\frac{15x^3y^2}{5xy}$
$\frac{32a^2b}{8ab^2}$
$\frac{45m^4n^3}{9m^2n}$

By working through these problems, you will gain confidence in your ability to simplify algebraic expressions. Remember to follow the step-by-step process we discussed earlier, and don't be afraid to make mistakes – they are a valuable learning opportunity. The more you practice, the more proficient you will become in simplifying algebraic expressions.
