1. Distributive Property Description: This property allows you to distribute multiplication over addition or subtraction. It’s often used to simplify expressions or to expand products in algebra. 2. Associative Property of Addition Description: The associative property of addition states that when adding three or more numbers, the way the numbers are grouped does not change the sum. This property is useful when rearranging terms for simplification. 3. Associative Property of Multiplication Description: The associative property of multiplication asserts that the grouping of numbers being multiplied does not affect the result. This is particularly useful in simplifying long products. 4. Commutative Property of Addition Description: The commutative property of addition states that the order of two numbers being added does not affect the sum. This is commonly used in rearranging terms in expressions. 5. Commutative Property of Multiplication Description: This property tells us that the order of multiplication does not affect the product. It's often used in simplifying expressions where the order of terms doesn’t matter. 6. Difference of Squares Description: The difference of squares formula allows you to factor expressions that are the difference between two perfect squares. This is often used to simplify equations or in solving quadratic equations. 7. Perfect Square Binomials Description: These formulas are used to expand squared binomials. They are commonly applied in factoring and solving quadratic equations or simplifying algebraic expressions. 8. Quadratic Formula Description: The quadratic formula is used to find the roots of any quadratic equation of the form. It is derived from completing the square and is one of the most powerful tools for solving quadratic equations. 9. Sum of Cubes Description: The sum of cubes formula allows you to factor expressions where you have the sum of two cubes. This formula is useful in algebraic manipulation and in solving cubic equations. 10. Product of Binomials Description: This formula shows how to multiply two binomials. The result is the sum of the products of each pair of terms from the two binomials. It’s often applied in expanding algebraic expressions and is foundational to understanding polynomial multiplication. 11. General Form for Factoring Quadratics This represents the general method of factoring quadratic equations. By finding two binomials whose product gives the original quadratic expression, you can simplify solving quadratic equations. Factorisation in algebra is the process of breaking down an expression or a number into its constituent parts, called factors, which when multiplied together give the original expression. Essentially, factorisation simplifies complex expressions by expressing them as a product of simpler terms.
