The factored form of an equation is the simplest form of the equation that is obtained by factoring out a common variable or constant from multiple terms. Many types of polynomials are presentable in factored form, but the more terms an equation contains, the more difficult it is to find common fact

In math, a prime factorization step diagram is a method of showing the steps used to determine the prime factors of a particular number. It is also known as a factor tree. A number is written on top with two of its factors below it, and the factors of those numbers below them, continuing until no nu
