यदि (7) और (8) समीकरण \(x^2-sx+p=0\) के मूल हैं, तो (s+p) का मान क्या है?
If (7) and (8) are roots of \(x^2-sx+p=0\), what is the value of (s+p)?
Explanation opens after your attempt
Correct Answer
A. (71)
Concept
The sum of roots gives (s=15) and the product gives (p=56). Therefore (s+p=71).
Why this answer is correct
The correct answer is A. (71). The sum of roots gives (s=15) and the product gives (p=56). Therefore (s+p=71).
Exam Tip
मूलों का योग (s=15) और गुणनफल (p=56) है। इसलिए (s+p=71) है।
