Worked Example
Revision challenge 9
For Class 9 Mathematics, explain or solve a factor theorem question from the chapter "Polynomials". Focus on revision challenge and show the working clearly.
Step-by-step solution path
- Read the topic idea: Factor Theorem.
- Recall the core explanation from the chapter: Polynomial expressions, zeroes, remainder theorem, factor theorem and algebraic identities.
- Use the related formula "Special: a³+b³+c³" as the main tool while solving.
- Write the reasoning in simple school-level language before the final answer.
Final learning answer
This example is centred on Factor Theorem. A strong solution should identify the correct data, apply Special: a³+b³+c³, and explain each transition instead of jumping directly to the answer.

Special: a³+b³+c³
If a+b+c=0, then a³+b³+c³ = 3abc
