The removed small square is (64), and the remaining part rearranges into ((x-8)(x+8)). In exams keep difference and square-difference models distinct.
Why this answer is correct
The correct answer is D. (x) बाय (x) वर्ग से (8) बाय (8) वर्ग हटाना / remove an (8) by (8) square from an (x) by (x) square. The removed small square is (64), and the remaining part rearranges into ((x-8)(x+8)). In exams keep difference and square-difference models distinct.
Exam Tip
हटा हुआ छोटा वर्ग (64) है और शेष भाग पुनर्व्यवस्थित होकर ((x-8)(x+8)) बनता है। परीक्षा में अंतर और वर्ग-अंतर के मॉडल अलग रखें।
