यदि \(\alpha,\beta\) समीकरण \(8x^2-31x+15=0\) के मूल हैं, तो \(\alpha\beta\) क्या है?
If \(\alpha,\beta\) are roots of \(8x^2-31x+15=0\), what is \(\alpha\beta\)?
Explanation opens after your attempt
Correct Answer
A. \( \frac{15}{8}\)
Concept
The product of roots is \(\frac{c}{a}=\frac{15}{8}\). In exams, use \(\frac{c}{a}\) for the product.
Why this answer is correct
The correct answer is A. \( \frac{15}{8}\). The product of roots is \(\frac{c}{a}=\frac{15}{8}\). In exams, use \(\frac{c}{a}\) for the product.
Exam Tip
मूलों का गुणनफल \(\frac{c}{a}=\frac{15}{8}\) है। परीक्षा में गुणनफल के लिए \(\frac{c}{a}\) का प्रयोग करें।
