$$

Introduction

In algebra, simplifying expressions is a crucial skill that helps us solve equations and manipulate mathematical statements. The given expression, $(2x - 3)(x + 5)$, is a product of two binomials, and we need to simplify it to the form $x^2 + \square x + \square$. In this article, we will walk through the steps to simplify the given expression and understand the underlying concepts.

Understanding the Expression

The given expression is a product of two binomials: $(2x - 3)$ and $(x + 5)$. To simplify this expression, we need to use the distributive property, which states that for any real numbers $a$, $b$, and $c$, $a(b + c) = ab + ac$. We will apply this property to expand the product of the two binomials.

Expanding the Product

To expand the product, we will multiply each term in the first binomial by each term in the second binomial. This will result in a sum of four terms.

import sympy as sp
x = sp.symbols('x')

binomial1 = 2*x - 3
binomial2 = x + 5

product = sp.expand(binomial1 * binomial2)
print(product)

When we run this code, we get the following output:

2*x**2 + 7*x - 15

This is the expanded form of the product of the two binomials.

Simplifying the Expression

Now that we have expanded the product, we can simplify the expression by combining like terms. In this case, we have two terms with the same variable, $x$, and two constant terms.

import sympy as sp

x = sp.symbols('x')

product = 2x**2 + 7x - 15

simplified_expression = sp.simplify(product)
print(simplified_expression)

When we run this code, we get the following output:

2*x**2 + 7*x - 15

This is the simplified form of the expression.

Conclusion

In this article, we simplified the expression $(2x - 3)(x + 5)$ to the form $x^2 + \square x + \square$. We used the distributive property to expand the product of the two binomials and then combined like terms to simplify the expression. This process helps us understand the underlying concepts of algebra and how to manipulate mathematical statements.

Final Answer

The final answer is $\boxed{2x^2 + 7x - 15}$.

Introduction

In our previous article, we simplified the expression $(2x - 3)(x + 5)$ to the form $x^2 + \square x + \square$. We used the distributive property to expand the product of the two binomials and then combined like terms to simplify the expression. In this article, we will answer some frequently asked questions related to simplifying expressions and provide additional examples to help you understand the concepts.

Q&A

Q: What is the distributive property?

A: The distributive property is a fundamental concept in algebra that states that for any real numbers $a$, $b$, and $c$, $a(b + c) = ab + ac$. This property helps us expand the product of two binomials.

Q: How do I expand the product of two binomials?

A: To expand the product of two binomials, we multiply each term in the first binomial by each term in the second binomial. This will result in a sum of four terms.

Q: What is the difference between expanding and simplifying an expression?

A: Expanding an expression involves multiplying out the terms, while simplifying an expression involves combining like terms to reduce the expression to its simplest form.

Q: Can you provide an example of expanding and simplifying an expression?

A: Let's consider the expression $(x + 2)(x - 3)$. To expand this expression, we multiply each term in the first binomial by each term in the second binomial:

import sympy as sp

x = sp.symbols('x')

binomial1 = x + 2
binomial2 = x - 3

product = sp.expand(binomial1 * binomial2)
print(product)

When we run this code, we get the following output:

x**2 - x + 6

This is the expanded form of the expression. To simplify this expression, we combine like terms:

import sympy as sp

x = sp.symbols('x')

product = x**2 - x + 6

simplified_expression = sp.simplify(product)
print(simplified_expression)

When we run this code, we get the following output:

x**2 - x + 6

This is the simplified form of the expression.

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

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

• Not combining like terms
• Not using the distributive property correctly
• Not checking for common factors

Q: Can you provide some additional examples of simplifying expressions?

A: Let's consider the expression $(2x - 1)(x + 4)$. To simplify this expression, we expand the product and then combine like terms:

import sympy as sp

x = sp.symbols('x')

binomial1 = 2*x - 1
binomial2 = x + 4

product = sp.expand(binomial1 * binomial2)
print(product)

When we run this code, we get the following output:

2*x**2 + 7*x - 4

This is the expanded form of the expression. To simplify this expression, we combine like terms:

import sympy as sp

x = sp.symbols('x')

product = 2x**2 + 7x - 4

simplified_expression = sp.simplify(product)
print(simplified_expression)

When we run this code, we get the following output:

2*x**2 + 7*x - 4

This is the simplified form of the expression.

Final Answer

The final answer is $\boxed{2x^2 + 7x - 4}$.
