Factoring

Definition

Factoring is the process of breaking down a mathematical expression, such as a polynomial or an algebraic expression, into a product of simpler factors. This technique is essential in various mathematical contexts, including the analysis of functions, limits, and asymptotes.

1. Factoring can be used to simplify expressions, solve equations, and analyze the behavior of functions.
2. Factoring a polynomial involves identifying the greatest common factor (GCF) and then using techniques such as grouping, trinomial factoring, or the difference of two squares.
3. Factoring can be particularly useful in the context of limits, as it can help simplify expressions and reveal the behavior of a function as it approaches a particular value.
4. The limit laws, such as the product rule and the quotient rule, often involve factoring to manipulate expressions and determine the limit of a function.
5. Factoring can also play a role in analyzing the asymptotic behavior of a function, as it can help identify the factors that contribute to the function's behavior at infinity.
