**Expanding and Simplifying Algebraic Expressions: A Step-by-Step Guide**

===========================================================

Introduction

Algebraic expressions are a fundamental concept in mathematics, and expanding and simplifying them is a crucial skill for students and professionals alike. In this article, we will focus on rewriting the expression $\left(x^3+\alpha^2\right)(12 \alpha-1)$ , which involves expanding and simplifying a product of two binomials.

Understanding the Expression

The given expression is a product of two binomials: $\left(x^3+\alpha^2\right)$ and $(12 \alpha-1)$ . To rewrite this expression, we need to apply the distributive property, which states that for any real numbers $a$ , $b$ , and $c$ , $a(b+c) = ab + ac$ .

Applying the Distributive Property

To expand the given expression, we will apply the distributive property to each term in the first binomial. This means that we will multiply each term in the first binomial by each term in the second binomial.

$\left(x^3+\alpha^2\right)(12 \alpha-1) = x^3(12 \alpha-1) + \alpha^2(12 \alpha-1)$

Expanding Each Term

Now, we will expand each term in the expression.

$x^3(12 \alpha-1) = 12x^3\alpha - x^3$

$\alpha^2(12 \alpha-1) = 12\alpha^3 - \alpha^2$

Combining Like Terms

After expanding each term, we can combine like terms to simplify the expression.

$12x^3\alpha - x^3 + 12\alpha^3 - \alpha^2$

Final Simplified Expression

The final simplified expression is:

$12x^3\alpha - x^3 + 12\alpha^3 - \alpha^2$

Conclusion

In this article, we have rewritten the expression $\left(x^3+\alpha^2\right)(12 \alpha-1)$ by applying the distributive property and expanding each term. We have also combined like terms to simplify the expression. This process demonstrates the importance of expanding and simplifying algebraic expressions in mathematics.

Introduction

Expanding and simplifying algebraic expressions is a crucial skill in mathematics, and it can be challenging to understand and apply the concepts. In this article, we will address some of the most frequently asked questions about expanding and simplifying algebraic expressions.

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 means that we can distribute a single term to multiple terms inside a parentheses.

Q: How do I apply the distributive property?

A: To apply the distributive property, we need to multiply each term in the first binomial by each term in the second binomial. For example, if we have the expression $(x+3)(2x+1)$ , we would multiply each term in the first binomial by each term in the second binomial:

$(x+3)(2x+1) = x(2x+1) + 3(2x+1)$

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

A: Expanding an algebraic expression involves applying the distributive property to multiply two or more binomials. Simplifying an algebraic expression involves combining like terms to reduce the expression to its simplest form.

Q: How do I combine like terms?

A: To combine like terms, we need to identify the terms that have the same variable and exponent. For example, if we have the expression $2x^2 + 3x^2 + 4x$ , we can combine the like terms $2x^2$ and $3x^2$ to get $5x^2$ . We can then combine the like terms $4x$ with the remaining terms to get $5x^2 + 4x$ .

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

A: Some common mistakes to avoid when expanding and simplifying algebraic expressions include:

Failing to apply the distributive property correctly
Not combining like terms
Not checking the expression for errors
Not using the correct order of operations
