Simplify The Expression:$2xx^4 - 2x^2y^2 + Y^4$

$$

Introduction

In algebra, simplifying expressions is a crucial skill that helps us solve equations and manipulate mathematical statements. The given expression, $2xx^4 - 2x^2y^2 + y^4$, appears to be a complex combination of terms, but with the right techniques, we can simplify it to a more manageable form. In this article, we will explore the steps involved in simplifying this expression and provide a clear understanding of the underlying mathematical concepts.

Understanding the Expression

Before we dive into simplifying the expression, let's take a closer look at its individual components. The expression consists of three terms:

1. $2xx^4$
2. $-2x^2y^2$
3. $y^4$

Each term has a unique combination of variables and exponents. To simplify the expression, we need to identify any common factors or patterns that can be used to combine these terms.

Factoring Out Common Factors

One of the most effective ways to simplify an expression is to factor out common factors. In this case, we can start by factoring out the common factor of $x^2$ from the first two terms:

$2xx^4 - 2x^2y^2 = 2x^2(x^2 - y^2)$

By factoring out $x^2$, we have simplified the first two terms and introduced a new expression, $x^2 - y^2$. This expression can be further simplified using the difference of squares formula.

Difference of Squares Formula

The difference of squares formula states that:

$a^2 - b^2 = (a + b)(a - b)$

Using this formula, we can rewrite the expression $x^2 - y^2$ as:

$x^2 - y^2 = (x + y)(x - y)$

Substituting this expression back into the simplified form of the first two terms, we get:

$2x^2(x^2 - y^2) = 2x^2(x + y)(x - y)$

Simplifying the Third Term

The third term, $y^4$, can be simplified by factoring out a common factor of $y^2$:

$y^4 = (y^2)^2 = (y^2)(y^2) = y^2y^2$

However, this simplification is not necessary, as we can leave the third term as is and combine it with the other two terms.

Combining the Terms

Now that we have simplified the first two terms and the third term, we can combine them to get the final simplified expression:

$2x^2(x + y)(x - y) + y^2y^2$

However, we can further simplify this expression by combining the last two terms:

$2x^2(x + y)(x - y) + y^4$

Final Simplified Expression

After carefully simplifying each term and combining them, we arrive at the final simplified expression:

$2x^2(x + y)(x - y) + y^4$

This expression is a significant improvement over the original expression, as it has been reduced to a more manageable form. The use of factoring and the difference of squares formula has allowed us to simplify the expression and reveal its underlying structure.

Conclusion

Simplifying expressions is a crucial skill in algebra that helps us solve equations and manipulate mathematical statements. By identifying common factors and using formulas such as the difference of squares, we can simplify complex expressions and reveal their underlying structure. In this article, we have explored the steps involved in simplifying the expression $2xx^4 - 2x^2y^2 + y^4$ and arrived at the final simplified expression. With practice and patience, you can master the art of simplifying expressions and become proficient in algebra.
