Introduction

Factorization is a fundamental concept in mathematics that involves expressing an algebraic expression as a product of simpler expressions. It is a crucial technique used to simplify complex expressions, solve equations, and identify patterns in mathematics. In this article, we will explore the factorization of two given expressions: $x^4 - y^4$ and $2a(3x - 2y) + 5b(2y - 3x)$ .

Factorization of $x^4 - y^4$

The expression $x^4 - y^4$ can be factored using the difference of squares formula. The difference of squares formula states that $a^2 - b^2 = (a + b)(a - b)$ .

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

Using the difference of squares formula, we can rewrite the expression as:

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

Now, we can factor the expression $x^2 - y^2$ using the difference of squares formula again:

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

Therefore, the final factorization of $x^4 - y^4$ is:

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

Factorization of $2a(3x - 2y) + 5b(2y - 3x)$

The expression $2a(3x - 2y) + 5b(2y - 3x)$ can be factored using the distributive property. The distributive property states that $a(b + c) = ab + ac$ .

2a(3x - 2y) + 5b(2y - 3x) = 6ax - 4ay + 10by - 15bx

Now, we can group the terms with the same variables together:

(6ax - 15bx) + (-4ay + 10by)

Next, we can factor out the common terms from each group:

3x(2a - 5b) - 2y(4a - 10b)

Therefore, the final factorization of $2a(3x - 2y) + 5b(2y - 3x)$ is:

3x(2a - 5b) - 2y(4a - 10b)

Conclusion

In this article, we have explored the factorization of two given expressions: $x^4 - y^4$ and $2a(3x - 2y) + 5b(2y - 3x)$ . We have used the difference of squares formula and the distributive property to simplify the expressions and identify their factors. Factorization is a powerful technique used in mathematics to simplify complex expressions and solve equations. By understanding the different factorization techniques, we can solve a wide range of mathematical problems and identify patterns in mathematics.
