STEP 1: Basic Concepts
🔹 What is Factorisation?
Factorisation is the process of writing a given number or algebraic expression as a product of its factors.
Factorisation is the process of writing a given number or algebraic expression as a product of its factors.
🔹 Factors
Factors are numbers or expressions which divide another number or expression exactly.
Example:
12 = 3 × 4
Here, 3 and 4 are factors of 12.

🔹 Algebraic Factors
In algebra, factorisation means splitting an expression into simpler expressions whose product gives the original expression.
Example:
x² + 5x = x(x + 5)
In algebra, factorisation means splitting an expression into simpler expressions whose product gives the original expression.
Example:
x² + 5x = x(x + 5)
🔹 Why is Factorisation Important?
- It simplifies algebraic expressions
- Helps in solving equations
- Makes calculations easier
- Very useful in higher classes
🔹 Types of Factorisation (Overview)
- Factorisation by taking common factors
- Factorisation by grouping
- Factorisation using identities
🎯 Quick Tip for Students:
Always look for a common factor first before using other methods.
