Simplify The Expression: $ \left(x^2-3\right)\left(x^5+2 X^3\right) $

$$

Introduction

In algebra, simplifying expressions is a crucial skill that helps us solve equations and manipulate mathematical statements. When we encounter a product of two or more expressions, we need to apply the distributive property to simplify it. In this article, we will focus on simplifying the expression $\left(x^2-3\right)\left(x^5+2 x^3\right)$ using the distributive property.

Understanding the Distributive Property

The distributive property is a fundamental concept in algebra that allows us to expand a product of two or more expressions. It states that for any real numbers $a$, $b$, and $c$, we have:

$$a(b+c) = ab + ac$$

This property can be extended to more than two expressions, and it is a powerful tool for simplifying complex expressions.

Applying the Distributive Property

To simplify the expression $\left(x^2-3\right)\left(x^5+2 x^3\right)$, we will apply the distributive property. We will multiply each term in the first expression by each term in the second expression, and then combine like terms.

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

We will start by multiplying the first term in the first expression, $x^2$, by each term in the second expression, $x^5$ and $2 x^3$. This gives us:

$$x^2 \cdot x^5 = x^{2+5} = x^7$$

$$x^2 \cdot 2 x^3 = 2 x^{2+3} = 2 x^5$$

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

Next, we will multiply the second term in the first expression, $-3$, by each term in the second expression, $x^5$ and $2 x^3$. This gives us:

$$-3 \cdot x^5 = -3 x^5$$

$$-3 \cdot 2 x^3 = -6 x^3$$

Step 3: Combine Like Terms

Now, we will combine the like terms that we obtained in the previous steps. We have:

$$x^7 + 2 x^5 - 3 x^5 - 6 x^3$$

We can combine the like terms $2 x^5$ and $-3 x^5$ to get:

$$x^7 - x^5 - 6 x^3$$

Conclusion

In this article, we simplified the expression $\left(x^2-3\right)\left(x^5+2 x^3\right)$ using the distributive property. We applied the distributive property to multiply each term in the first expression by each term in the second expression, and then combined like terms to obtain the simplified expression. This process is a crucial skill in algebra that helps us solve equations and manipulate mathematical statements.
