Introduction

When dealing with fractions, there are several properties that can be used to simplify complex expressions. One of these properties is the sum of fractions, which states that $\frac{a+b}{c}=\frac{a}{c}+\frac{b}{c}$ . This property can be used to divide an expression by a binomial, making it easier to simplify and solve. In this article, we will use this property to divide the expression $\frac{25x^3-2x}{5x}$ .

The Property of a Fraction

The property of a fraction that we will be using is $\frac{a+b}{c}=\frac{a}{c}+\frac{b}{c}$ . This property can be used to divide an expression by a binomial, making it easier to simplify and solve. To use this property, we need to identify the binomial that we want to divide by and then apply the property.

Dividing the Expression

To divide the expression $\frac{25x^3-2x}{5x}$ , we need to identify the binomial that we want to divide by. In this case, the binomial is $5x$ . We can then apply the property of a fraction to divide the expression.

$\frac{25x^3-2x}{5x} = \frac{25x^3}{5x} - \frac{2x}{5x}$

Simplifying the Expression

Now that we have divided the expression using the property of a fraction, we can simplify it further. To simplify the expression, we need to divide the numerator and denominator of each fraction by their greatest common divisor (GCD).

$\frac{25x^3}{5x} - \frac{2x}{5x} = 5x^2 - \frac{2}{5}$

Conclusion

In this article, we used the property of a fraction to divide the expression $\frac{25x^3-2x}{5x}$ . We identified the binomial that we wanted to divide by and then applied the property to divide the expression. We then simplified the expression further by dividing the numerator and denominator of each fraction by their GCD. The final simplified expression is $5x^2 - \frac{2}{5}$ .

Step-by-Step Solution

Here is the step-by-step solution to the problem:

Identify the binomial that we want to divide by: $5x$
Apply the property of a fraction: $\frac{25x^3-2x}{5x} = \frac{25x^3}{5x} - \frac{2x}{5x}$
Simplify the expression: $5x^2 - \frac{2}{5}$

Final Answer

The final answer is $\boxed{5x^2 - \frac{2}{5}}$ .

Discussion

The property of a fraction is a powerful tool that can be used to simplify complex expressions. By identifying the binomial that we want to divide by and then applying the property, we can divide an expression by a binomial and simplify it further. This property can be used in a variety of mathematical applications, including algebra and calculus.

Example Problems

Here are a few example problems that demonstrate the use of the property of a fraction:

Divide the expression $\frac{9x^2-4}{3x}$ using the property of a fraction.
Simplify the expression $\frac{16x^3-9x}{4x}$ using the property of a fraction.
Divide the expression $\frac{25x^2-16}{5x}$ using the property of a fraction.

Solutions to Example Problems

Here are the solutions to the example problems:

Divide the expression $\frac{9x^2-4}{3x}$ using the property of a fraction: $\frac{9x^2-4}{3x} = \frac{9x^2}{3x} - \frac{4}{3x} = 3x - \frac{4}{3x}$
Simplify the expression $\frac{16x^3-9x}{4x}$ using the property of a fraction: $\frac{16x^3-9x}{4x} = \frac{16x^3}{4x} - \frac{9x}{4x} = 4x^2 - \frac{9}{4x}$
Divide the expression $\frac{25x^2-16}{5x}$ using the property of a fraction: $\frac{25x^2-16}{5x} = \frac{25x^2}{5x} - \frac{16}{5x} = 5x - \frac{16}{5x}$
