Introduction

In algebra, simplifying complex expressions is a crucial skill that helps us solve equations and inequalities. One common type of expression is a binomial divided by a monomial. In this article, we will explore how to simplify such expressions using the concept of division. We will use a specific example to illustrate the process and provide a step-by-step guide on how to arrive at the correct answer.

Understanding Binomials and Monomials

Before we dive into the example, let's briefly define what binomials and monomials are.

Binomial: A binomial is an algebraic expression consisting of two terms. It can be written in the form of $ax + by$ , where $a$ and $b$ are constants, and $x$ and $y$ are variables.
Monomial: A monomial is an algebraic expression consisting of a single term. It can be written in the form of $ax^n$ , where $a$ is a constant, and $n$ is a positive integer.

The Example

Let's consider the following expression:

\frac{-38 c^2 y + 1460^{\circ} y}{-4 x^2 y} = \square

Our goal is to simplify this expression by dividing the binomial by the monomial.

Step 1: Factor Out the Common Term

The first step in simplifying the expression is to factor out the common term from the binomial. In this case, the common term is $y$ . We can factor out $y$ from both terms:

\frac{-38 c^2 y + 1460^{\circ} y}{-4 x^2 y} = \frac{y(-38 c^2 + 1460^{\circ})}{-4 x^2 y}

Step 2: Cancel Out the Common Factor

Now that we have factored out the common term, we can cancel out the common factor between the numerator and the denominator. In this case, the common factor is $y$ . We can cancel out $y$ from both the numerator and the denominator:

\frac{y(-38 c^2 + 1460^{\circ})}{-4 x^2 y} = \frac{-38 c^2 + 1460^{\circ}}{-4 x^2}

Step 3: Simplify the Expression

Now that we have canceled out the common factor, we can simplify the expression by dividing the numerator by the denominator. In this case, we can divide $-38 c^2 + 1460^{\circ}$ by $-4 x^2$ :

\frac{-38 c^2 + 1460^{\circ}}{-4 x^2} = \frac{-38 c^2}{-4 x^2} + \frac{1460^{\circ}}{-4 x^2}

Step 4: Simplify the Fractions

Now that we have divided the numerator by the denominator, we can simplify the fractions by dividing both the numerator and the denominator by their greatest common divisor (GCD). In this case, the GCD of $-38 c^2$ and $-4 x^2$ is $-2$ . We can divide both the numerator and the denominator by $-2$ :

\frac{-38 c^2}{-4 x^2} + \frac{1460^{\circ}}{-4 x^2} = \frac{19 c^2}{2 x^2} + \frac{730^{\circ}}{2 x^2}

Conclusion

In this article, we have explored how to simplify complex algebraic expressions using the concept of division. We have used a specific example to illustrate the process and provided a step-by-step guide on how to arrive at the correct answer. By following these steps, you can simplify complex expressions and arrive at the correct answer.

Final Answer

The final answer is:

\frac{19 c^2}{2 x^2} + \frac{730^{\circ}}{2 x^2}$$<br/> **Simplifying Complex Algebraic Expressions: A Q&A Guide** ===========================================================
