एक वर्ग मॉडल \(x^2-10x+q\) को पूर्ण वर्ग दिखाता है। यदि हटाई गई प्रत्येक पट्टी (5x) की है तो (q) क्या होगा?
A square model \(x^2-10x+q\) shows a perfect square. If each removed strip has area (5x), what is (q)?
Explanation opens after your attempt
C. (25)overlap square
Concept
Two (5x) strips are removed and the (5) by (5) overlap is added back. In exams the last term in a subtraction square is the square of the strip width.
Why this answer is correct
The correct answer is C. (25) / overlap square. Two (5x) strips are removed and the (5) by (5) overlap is added back. In exams the last term in a subtraction square is the square of the strip width.
Exam Tip
दो (5x) पट्टियां हटती हैं और (5) बाय (5) ओवरलैप वापस जुड़ता है। परीक्षा में घटाव वर्ग में अंतिम पद पट्टी की चौड़ाई का वर्ग होता है।
