what is factorisation??
Answers
Answer:
it is simply the resolution of an integer or polynomial into factors such that when multiplied together they will result in original or initial the integer or polynomial. In the factorisation method, we reduce any algebraic or quadratic equation into its simpler form, where the equations are represented as the product of factors instead of expanding the brackets. The factors of any equation can be an integer, a variable or an algebraic expression itself.

What is a Factor?
It is something that is to be multiplied in an expression.
Product = factor × factor
Basic Factorisation Formula
- a² – b² = (a – b)(a + b)
- (a + b)² = a² + 2ab + b²
- (a – b)² = a² – 2ab + b²
- a³ – b³ = (a – b)(a² + ab + b²)
- a³ + b³ = (a + b)(a² – ab + b²)
- (a + b + c)2 = a² + b² + c² + 2ab + 2bc + 2ca
- (a – b – c)2 = a² + b² + c² – 2ab + 2bc – 2ca
