भुजा (5p-2q) वाले वर्ग के मॉडल में अंतिम कोना और मध्य क्षेत्रफल क्रमशः क्या होंगे?
In the model of a square with side (5p-2q), what will be the corner term and the middle area respectively?
Explanation opens after your attempt
C. \(4q^2\) और (-20pq)corner and middle
Concept
The corner is ((2q)2=4q-2), and the middle area is (2\cdot5p\cdot(-2q)=-20pq). In exams the corner area can remain a positive square.
Why this answer is correct
The correct answer is C. \(4q^2\) और (-20pq) / corner and middle. The corner is ((2q)2=4q-2), and the middle area is (2\cdot5p\cdot(-2q)=-20pq). In exams the corner area can remain a positive square.
Exam Tip
कोना ((2q)2=4q-2) और मध्य क्षेत्रफल (2\cdot5p\cdot(-2q)=-20pq) है। परीक्षा में कोने का क्षेत्रफल हमेशा धनात्मक वर्ग हो सकता है।
