समीकरण \(2x^2-7x+3=0\) के मूलों के व्युत्क्रमों का योग क्या है?
What is the sum of reciprocals of the roots of \(2x^2-7x+3=0\)?
Explanation opens after your attempt
Correct Answer
A. \(\frac{7}{3}\)
Concept
The sum of reciprocals is \(\frac{\alpha+\beta}{\alpha\beta}\). Here \(\frac{\frac{7}{2}}{\frac{3}{2}}=\frac{7}{3}\).
Why this answer is correct
The correct answer is A. \(\frac{7}{3}\). The sum of reciprocals is \(\frac{\alpha+\beta}{\alpha\beta}\). Here \(\frac{\frac{7}{2}}{\frac{3}{2}}=\frac{7}{3}\).
Exam Tip
व्युत्क्रमों का योग \(\frac{\alpha+\beta}{\alpha\beta}\) होता है। यहां \(\frac{\frac{7}{2}}{\frac{3}{2}}=\frac{7}{3}\) है।
