When a number, or polynomial in algebra, can be expressed as the product of two numbers or polynomials, these are factors of the first. Expressing a number of polynomial as a product of its factors is known as factorising.

Example: 1, 2, 3, 4, 6 and 12 are all factors of 12.

Example: (x-1) and (x+4) are factors of (x²+ 3x - 4).

Imperial measurements are rarely used in modern times.

Formula
