Factoring (a-b)^3+(b-c)^3+(c-a)^3
This article will explore the solution to the factorization of the expression: (a-b)^3 + (b-c)^3 + (c-a)^3.
Understanding the Problem
We need to find a way to rewrite the given expression as a product of simpler expressions. This factorization can be useful in solving equations, simplifying expressions, and other algebraic manipulations.
The Solution
The key to solving this problem lies in recognizing a pattern and using a helpful algebraic identity.
1. Identifying the Pattern:
Notice that the expression consists of three cubes, each representing the difference of two variables. This hints that we might be able to use the following algebraic identity:
x^3 + y^3 + z^3 - 3xyz = (x + y + z)(x^2 + y^2 + z^2 - xy - xz - yz)
2. Applying the Identity:
To apply the identity, we need to manipulate our expression slightly:
(a-b)^3 + (b-c)^3 + (c-a)^3 = [(a-b) + (b-c) + (c-a)][(a-b)^2 + (b-c)^2 + (c-a)^2 - (a-b)(b-c) - (a-b)(c-a) - (b-c)(c-a)]
3. Simplifying:
Notice that the first bracket simplifies to zero. Therefore:
(a-b)^3 + (b-c)^3 + (c-a)^3 = 0
4. The Final Result:
Thus, the factorization of the expression (a-b)^3 + (b-c)^3 + (c-a)^3 is simply 0. This means the expression is always equal to zero for any values of a, b, and c.
Conclusion
By applying the algebraic identity for the sum of cubes and recognizing the pattern in the given expression, we were able to successfully factorize it and arrive at the result of 0. This demonstrates the power of algebraic identities in simplifying and solving complex expressions.
