Factoring

Factoring is the process of finding the numbers or algebraic expressions that multiply together to give a particular number or expression. It is an important concept in mathematics and is used in various areas such as algebra, number theory, and calculus.

Types of Factoring

There are several types of factoring, including:

1. Factorization of Integers: Finding the prime factors of a given integer. For example, the prime factorization of 12 is 2 * 2 * 3.
2. Factoring Algebraic Expressions: Breaking down algebraic expressions into simpler factors. For example, factoring the expression x^2 - 4 results in (x - 2)(x + 2).
3. Factoring Quadratic Expressions: Finding the factors of quadratic expressions of the form ax^2 + bx + c. For example, factoring the expression x^2 + 5x + 6 results in (x + 2)(x + 3).

Methods of Factoring

There are various methods for factoring algebraic expressions, including:

• Common Factor: Factoring out the greatest common factor from an expression.
• Factoring by Grouping: Grouping terms in an expression and factoring common factors from each group.
• Factoring Quadratic Expressions: Using methods such as the difference of squares, perfect square trinomials, and the quadratic formula to factor quadratic expressions.
