Introduction
In mathematics, factorization is a fundamental concept that involves breaking down complex expressions into simpler ones. It is a crucial skill for solving equations, simplifying expressions, and understanding various mathematical concepts. In this article, we will delve into the factorization of the expression 8z³-(x-y)³-(y+z)³-(z-x)³. We will explore the steps involved in factorizing this expression and provide a detailed explanation of the process.
Understanding the Expression
The given expression is 8z³-(x-y)³-(y+z)³-(z-x)³. At first glance, this expression may seem complex and daunting. However, by breaking it down into smaller components, we can simplify it and factorize it. Let's start by understanding the individual components of the expression.
- 8z³: This is a simple cubic expression where 8 is the coefficient and z is the variable.
- (x-y)³: This is a cubic expression in terms of x and y, where the difference between x and y is cubed.
- (y+z)³: This is another cubic expression in terms of y and z, where the sum of y and z is cubed.
- (z-x)³: This is a cubic expression in terms of z and x, where the difference between z and x is cubed.
Factorizing the Expression
To factorize the given expression, we can start by grouping the terms that have common factors. Let's group the first two terms and the last two terms separately.
8z³ - (x-y)³ - (y+z)³ - (z-x)³
= (8z³ - (x-y)³) - (y+z)³ - (z-x)³
Now, let's focus on the first group, 8z³ - (x-y)³. We can factor out a common factor of (x-y) from the second term.
8z³ - (x-y)³
= 8z³ - (x-y)(x-y)(x-y)
= 8z³ - (x-y)³
However, we can rewrite the first term as 8z³ = (x-y)(x-y)(x-y)(2z). This allows us to factor out a common factor of (x-y) from both terms.
8z³ - (x-y)³
= (x-y)(x-y)(x-y)(2z) - (x-y)(x-y)(x-y)
= (x-y)(x-y)(x-y)(2z - 1)
Now, let's focus on the second group, (y+z)³ - (z-x)³. We can factor out a common factor of (z-x) from the second term.
(y+z)³ - (z-x)³
= (y+z)³ - (z-x)(z-x)(z-x)
= (y+z)³ - (z-x)³
However, we can rewrite the first term as (y+z)³ = (z-x)(z-x)(z-x)(y+z). This allows us to factor out a common factor of (z-x) from both terms.
(y+z)³ - (z-x)³
= (z-x)(z-x)(z-x)(y+z) - (z-x)(z-x)(z-x)
= (z-x)(z-x)(z-x)(y+z - 1)
Combining the Groups
Now that we have factorized the two groups, we can combine them to get the final factorized expression.
(x-y)(x-y)(x-y)(2z - 1) - (z-x)(z-x)(z-x)(y+z - 1)
However, we can simplify this expression further by combining the two groups.
(x-y)(x-y)(x-y)(2z - 1) - (z-x)(z-x)(z-x)(y+z - 1)
= (x-y)(x-y)(x-y)(2z - 1) + (z-x)(z-x)(z-x)(1 - (y+z))
= (x-y)(x-y)(x-y)(2z - 1) + (z-x)(z-x)(z-x)(1 - (x+y))
Final Factorized Expression
After simplifying the expression, we get the final factorized form.
(x-y)(x-y)(x-y)(2z - 1) + (z-x)(z-x)(z-x)(1 - (x+y))
However, we can rewrite this expression in a more compact form.
(x-y)(x-y)(x-y)(2z - 1) + (z-x)(z-x)(z-x)(1 - x - y)
= (x-y)(x-y)(x-y)(2z - 1) + (z-x)(z-x)(z-x)(-x - y + 1)
= (x-y)(x-y)(x-y)(2z - 1) - (z-x)(z-x)(z-x)(x + y - 1)
Conclusion
In this article, we factorized the expression 8z³-(x-y)³-(y+z)³-(z-x)³. We broke down the expression into smaller components, grouped the terms, and factorized each group separately. Finally, we combined the groups to get the final factorized expression. The factorized form of the expression is (x-y)(x-y)(x-y)(2z - 1) - (z-x)(z-x)(z-x)(x + y - 1). This expression can be used to simplify complex equations and understand various mathematical concepts.
