यदि \(x^2+2xy+y^2\) के मॉडल में (xy) आयतों की जगह गलती से केवल एक (xy) लिया जाए तो कौन-सा गलत परिणाम मिलेगा?
If in the model of \(x^2+2xy+y^2\), only one (xy) rectangle is mistakenly taken, what wrong result will be obtained?
Explanation opens after your attempt
Correct Answer
A. \(x^2+xy+y^2\)one rectangle partial
Concept
The full model has two (xy) rectangles, so missing one gives \(x^2+xy+y^2\). In exams always check the two parts of the middle term.
Why this answer is correct
The correct answer is A. \(x^2+xy+y^2\) / one rectangle partial. The full model has two (xy) rectangles, so missing one gives \(x^2+xy+y^2\). In exams always check the two parts of the middle term.
Exam Tip
पूर्ण मॉडल में दो (xy) आयत होते हैं, एक छोड़ने पर \(x^2+xy+y^2\) मिलता है। परीक्षा में मध्य पद के दो भाग हमेशा जांचें।
