यदि \(x^2+px+36\) पूर्ण वर्ग हो और (p) धनात्मक हो, तो (p) का मान क्या होगा?
If \(x^2+px+36\) is a perfect square and (p) is positive, what is the value of (p)?
Explanation opens after your attempt
C. (12)
Concept
Since \(36=6^2\), the middle term will be \(2\cdot6\cdot x=12x\). Exam tip: double the square root of the constant term.
Why this answer is correct
The correct answer is C. (12). Since \(36=6^2\), the middle term will be \(2\cdot6\cdot x=12x\). Exam tip: double the square root of the constant term.
Exam Tip
\(36=6^2\) है इसलिए मध्य पद \(2\cdot6\cdot x=12x\) होगा। परीक्षा में अंतिम पद की वर्गमूल को दोगुना करें।
