यदि \(x^2+2xy+y^2\) को क्षेत्रफल मॉडल से समझाया जाए, तो बाहरी भुजा क्या होगी?
If \(x^2+2xy+y^2\) is explained by an area model, what will be the outer side?
Explanation opens after your attempt
B. (x+y)
Concept
This is the expansion of ((x+y)2), so the outer side is (x+y). Exam tip: look for two (xy) rectangles.
Why this answer is correct
The correct answer is B. (x+y). This is the expansion of ((x+y)2), so the outer side is (x+y). Exam tip: look for two (xy) rectangles.
Exam Tip
यह ((x+y)2) का विस्तार है इसलिए बाहरी भुजा (x+y) है। परीक्षा में दो (xy) आयत देखें।
