Lesson

Higher Expressions and Applications

Cubic expressions such as a³ + b³ and a³ – b³ can be factorized using standard identities. More complex cubic polynomials can often be factorized using grouping or by finding one known factor, usually via trial substitution. Once one factor is found, polynomial division is used to reduce the expression.

Concept

Factor Theorem

If f(k) = 0 for a polynomial f(x), then (x − k) is a factor of f(x). This helps identify roots and factors quickly. 💡 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
