यदि (4) और (5) समीकरण \(x^2-sx+p=0\) के मूल हैं, तो (s+p) का मान क्या है?
If (4) and (5) are roots of \(x^2-sx+p=0\), what is the value of (s+p)?
Explanation opens after your attempt
A. (29)
Concept
The sum of roots gives (s=9) and the product gives (p=20). Therefore (s+p=29).
Why this answer is correct
The correct answer is A. (29). The sum of roots gives (s=9) and the product gives (p=20). Therefore (s+p=29).
Exam Tip
मूलों का योग (s=9) और गुणनफल (p=20) है। इसलिए (s+p=29) है।
