Introduction

Multiplying and simplifying algebraic expressions is a fundamental concept in mathematics, particularly in algebra. It involves multiplying two or more expressions together and then simplifying the resulting expression to its simplest form. In this article, we will focus on multiplying and simplifying the expression $\left(x^2+3x+1\right)\left(x^2+4x+2\right)$.

Understanding the Concept of Multiplying Algebraic Expressions

To multiply two algebraic expressions, we need to follow the distributive property, which states that for any real numbers $a$, $b$, and $c$, $a(b+c) = ab + ac$. This means that we need to multiply each term in the first expression by each term in the second expression and then combine like terms.

Step 1: Multiply Each Term in the First Expression by Each Term in the Second Expression

To multiply the expression $\left(x^2+3x+1\right)\left(x^2+4x+2\right)$, we need to multiply each term in the first expression by each term in the second expression.

$\left(x^2+3x+1\right)\left(x^2+4x+2\right)$

$= x^2(x^2+4x+2) + 3x(x^2+4x+2) + 1(x^2+4x+2)$

Step 2: Multiply Each Term in the First Expression by Each Term in the Second Expression (Continued)

Now, we need to multiply each term in the first expression by each term in the second expression.

$= x^2(x^2+4x+2) + 3x(x^2+4x+2) + 1(x^2+4x+2)$

$= x^2(x^2) + x^2(4x) + x^2(2) + 3x(x^2) + 3x(4x) + 3x(2) + 1(x^2) + 1(4x) + 1(2)$

Step 3: Simplify the Expression

Now, we need to simplify the expression by combining like terms.

$= x^2(x^2) + x^2(4x) + x^2(2) + 3x(x^2) + 3x(4x) + 3x(2) + 1(x^2) + 1(4x) + 1(2)$

$= x^4 + 4x^3 + 2x^2 + 3x^3 + 12x^2 + 6x + x^2 + 4x + 2$

Step 4: Combine Like Terms

Now, we need to combine like terms.

$= x^4 + 4x^3 + 2x^2 + 3x^3 + 12x^2 + 6x + x^2 + 4x + 2$

$= x^4 + (4x^3 + 3x^3) + (2x^2 + 12x^2 + x^2) + (6x + 4x) + 2$

$= x^4 + 7x^3 + 15x^2 + 10x + 2$

Conclusion

In conclusion, the final answer to the expression $\left(x^2+3x+1\right)\left(x^2+4x+2\right)$ is $x^4 + 7x^3 + 15x^2 + 10x + 2$. This is the simplified form of the expression, and it is in standard form.

Q&A: Multiplying and Simplifying Algebraic Expressions

Q: What is the distributive property?

A: The distributive property is a mathematical concept that states that for any real numbers $a$, $b$, and $c$, $a(b+c) = ab + ac$. This means that when you multiply a single term by a binomial, you can multiply each term in the binomial by the single term and then combine like terms.

Q: How do I multiply two algebraic expressions?

A: To multiply two algebraic expressions, you need to follow the distributive property, which means multiplying each term in the first expression by each term in the second expression and then combining like terms.

Q: What is the difference between multiplying and simplifying algebraic expressions?

A: Multiplying algebraic expressions involves multiplying two or more expressions together, while simplifying algebraic expressions involves combining like terms to get the simplest form of the expression.

Q: How do I simplify an algebraic expression?

A: To simplify an algebraic expression, you need to combine like terms. This involves adding or subtracting the coefficients of the same variables.

Q: What is the final answer to the expression $\left(x^2+3x+1\right)\left(x^2+4x+2\right)$?

A: The final answer to the expression $\left(x^2+3x+1\right)\left(x^2+4x+2\right)$ is $x^4 + 7x^3 + 15x^2 + 10x + 2$.

Q: How do I multiply a binomial by a trinomial?

A: To multiply a binomial by a trinomial, you need to follow the distributive property, which means multiplying each term in the binomial by each term in the trinomial and then combining like terms.

Q: What is the difference between multiplying and factoring algebraic expressions?

A: Multiplying algebraic expressions involves multiplying two or more expressions together, while factoring algebraic expressions involves expressing an expression as a product of simpler expressions.

Q: How do I factor an algebraic expression?

A: To factor an algebraic expression, you need to identify the greatest common factor (GCF) of the terms and then express the expression as a product of the GCF and the remaining terms.
