What is expand in math?

In mathematics, the term 'expand' refers to the process of multiplying out a mathematical expression to make it more detailed or to simplify it.

How to expand using the distributive property?

To expand an expression using the distributive property, multiply each term inside a set of parentheses by each term outside the parentheses, and then simplify by combining like terms.

The FOIL method is a mnemonic used to help remember the steps for multiplying two binomials. FOIL stands for 'First, Outer, Inner, Last', and refers to the order in which you multiply the terms of the two binomials to get the expanded expression.

What is the perfect square rule?

The perfect square rule is a technique used to expand expressions that are the sum or difference of two squares, such as (a + b)^2 or (a - b)^2. The rule states that the square of the sum (or difference) of two terms is equal to the sum (or difference) of the squares of the terms plus twice the product of the terms.
