Common Factor Method

The most basic method of factorization is taking out the Highest Common Factor (HCF) from each term. For example, in 6x² + 3x, the common factor is 3x, so the expression becomes 3x(2x + 1). This method simplifies expressions and often leads to further factorization.

Concept

Meaning of Factorisation

Factorisation breaks a polynomial into factors that multiply to give the original expression. 💡 Exam Tip: Always look for a common factor first. For quadratics, check whether splitting the middle term works before moving to longer methods. ⚠️ Common Mistake: Students often stop after partial factorisation and forget to factor the remaining expression completely. 📌 Trigger: Common factor first
