Mathematically, the relationship between factor × factor = product is called solution, and mathematically, the relationship between factor × factor = product is called multiplication. The multiplication formula can be used not only for polynomial multiplication from left to right, but also for factorization from right to left. Factorization and polynomial multiplication are inverse operations. Remember some important formula variants and their inverse division.

Factor x factor = product:

Factor times factor equals product. The concept of product depends on the definition of "multiplication". When people upgrade the set of multiplication objects to more general sets, such as groups, rings, fields, etc. The concept of the product will also change.

Product is the name of many different concepts in mathematics. In arithmetic, the result of multiplication of two or more numbers is called their product or product. When the multiplied numbers are real numbers or complex numbers, the order of multiplication has no effect on the product, which is called commutativity.

The simple operation of finding the sum of several identical addends is called multiplication. Multiplication of two numbers is called factor, and multiplication is called product. In mathematics, the relationship that the factor x equals the product is called the relationship between the parts of multiplication. When the product is a quaternion or matrix, or an element in some algebraic structures, the order will affect the result of the product.
