यदि \(x^2+6x+9\) का मॉडल पूर्ण वर्ग है तो दो समान आयताकार पट्टियों में प्रत्येक का क्षेत्रफल क्या होगा?
If the model of \(x^2+6x+9\) is a perfect square, what is the area of each of the two equal rectangular strips?
Explanation opens after your attempt
A. (3x)each strip
Concept
The total middle term is (6x), so each strip is (3x). In exams divide the middle term into two equal parts in a perfect square.
Why this answer is correct
The correct answer is A. (3x) / each strip. The total middle term is (6x), so each strip is (3x). In exams divide the middle term into two equal parts in a perfect square.
Exam Tip
कुल मध्य पद (6x) है इसलिए प्रत्येक पट्टी (3x) है। परीक्षा में पूर्ण वर्ग में मध्य पद को दो बराबर भागों में बांटें।
