यदि \(x^2+12x+36\) एक पूर्ण वर्ग क्षेत्र मॉडल है तो पूरी भुजा क्या होगी?
If \(x^2+12x+36\) is a perfect square area model, what is the whole side?
Explanation opens after your attempt
B. (x+6)
Concept
\(36=6^2\) and \(12x=2\cdot6x\). So the whole side is (x+6).
Why this answer is correct
The correct answer is B. (x+6). \(36=6^2\) and \(12x=2\cdot6x\). So the whole side is (x+6).
Exam Tip
\(36=6^2\) और \(12x=2\cdot6x\) है। इसलिए पूरी भुजा (x+6) होगी।
