im not sure if you still want this but,
Factorisation is a process in mathematics where an expression or number is written as a product of several factors. It is used in algebra to simplify equations and expressions, for example by taking out common factors or writing a number as a product of its prime factors. It can also be used to solve quadratic equations by factoring the equation into two linear factors. To use factorisation, the first step is to identify any common factors between the terms of the expression or equation, and then take them out. For example, if you have an expression such as 3x2y2 + 6x2y, you can factorise it by taking out the common factor of x2y, giving you x2y(3+6).
