यदि \(x^2-23x+q=0\) का एक मूल (9) है, तो (q) का मान क्या होगा?
If one root of \(x^2-23x+q=0\) is (9), what is the value of (q)?
Explanation opens after your attempt
Correct Answer
A. (126)
Concept
The other root is (14), so \(q=9\times14=126\). In exams, when (a=1), the constant term is the product of roots.
Why this answer is correct
The correct answer is A. (126). The other root is (14), so \(q=9\times14=126\). In exams, when (a=1), the constant term is the product of roots.
Exam Tip
दूसरा मूल (14) है, इसलिए \(q=9\times14=126\) होगा। परीक्षा में (a=1) हो तो स्थिर पद मूलों का गुणनफल होता है।
