Factorization of Grouping and Transposition of Formulas in Math

Algebra is built on expressions and equations. An expression is a combination of numbers, variables, and operation signs (like 2x + 5). An equation sets two expressions equal to each other (like 2x + 5 = 11). Your main goal in algebra is often to "solve" an equation, meaning finding the value of the variable that makes the equation true.

A variable is a symbol, typically a letter (like x, y, a), that represents an unknown number. It's a placeholder.

Factorization by grouping is a technique you use when an expression has four or more terms and you can't find a single common factor for all of them. The trick is to group terms that do share common factors.
