यदि \(x^2-2kx+k^2\) को घटाव वाले वर्ग मॉडल से बनाया गया है, तो भुजा क्या होगी?
If \(x^2-2kx+k^2\) is made by a subtraction square model, what will be the side?
Explanation opens after your attempt
A. (x-k)
Concept
Two (kx) strips are subtracted and the \(k^2\) corner is added back. In exams, identify (x-k) from (-2kx).
Why this answer is correct
The correct answer is A. (x-k). Two (kx) strips are subtracted and the \(k^2\) corner is added back. In exams, identify (x-k) from (-2kx).
Exam Tip
दो (kx) पट्टियाँ घटती हैं और \(k^2\) कोना वापस जुड़ता है। परीक्षा में (-2kx) से (x-k) पहचानें।
