For Class 12 Mathematics, explain or solve a plane equation question from the chapter "Three Dimensional Geometry". Focus on revision challenge and show the working clearly.
Step-by-step solution path
Read the topic idea: Plane equation.
Recall the core explanation from the chapter: Mathematics syllabus chapter for Class 12.
Use the related formula "lยฒ+mยฒ+nยฒ = 1" 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 Plane equation. A strong solution should identify the correct data, apply lยฒ+mยฒ+nยฒ = 1, and explain each transition instead of jumping directly to the answer.
