एक बड़े वर्ग से (4x) और (4x) क्षेत्रफल वाली दो पट्टियां हटाकर (16) क्षेत्रफल का कोना वापस जोड़ा गया। यदि मूल वर्ग \(x^2\) था तो बना क्षेत्रफल किसके बराबर है?
Two strips of areas (4x) and (4x) are removed from a large square and a corner of area (16) is added back. If the original square was \(x^2\), the resulting area equals what?
Explanation opens after your attempt
Correct Answer
B. \(x^2-8x+16\)
Concept
Two (4x) strips are subtracted and the common corner (16) is added back. Exam tip: recognize the ((x-4)2) model.
Why this answer is correct
The correct answer is B. \(x^2-8x+16\). Two (4x) strips are subtracted and the common corner (16) is added back. Exam tip: recognize the ((x-4)2) model.
Exam Tip
दो (4x) पट्टियां घटती हैं और साझा कोना (16) वापस जुड़ता है। परीक्षा में ((x-4)2) मॉडल को पहचानें।
