1. The problem is to provide a clear, detailed answer that would earn 3 marks on a typical math question. 2. To achieve 3 marks, the answer must include a clear statement of the problem, the relevant formula or method, and a complete, step-by-step solution with explanations. 3. For example, if the problem is to solve a quadratic equation $ax^2 + bx + c = 0$, the formula used is the quadratic formula: $$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$ 4. Important rules include: - Calculate the discriminant $\Delta = b^2 - 4ac$ to determine the nature of the roots. - Simplify the square root and the fraction carefully. 5. Show all intermediate steps, such as substituting values, simplifying under the square root, and simplifying the fraction. 6. Explain each step in plain language so the learner understands why each operation is performed. This approach ensures a complete, well-explained answer worthy of 3 marks.
