यदि \(x^2-7x+10=0\) के मूल \(\alpha\) और \(\beta\) हैं तो \(\frac{\alpha+\beta}{\alpha-\beta}\) का संभावित मान क्या है?
If \(\alpha\) and \(\beta\) are roots of \(x^2-7x+10=0\), what can be the value of \(\frac{\alpha+\beta}{\alpha-\beta}\)?
Explanation opens after your attempt
Correct Answer
B. \(\frac{7}{3}\) या \(-\frac{7}{3}\)\(\frac{7}{3}\) or \(-\frac{7}{3}\)
Concept
The roots are (5) and (2), so the sum is (7) and the difference can be \(\pm3\). Hence the value is \(\frac{7}{3}\) or \(-\frac{7}{3}\).
Why this answer is correct
The correct answer is B. \(\frac{7}{3}\) या \(-\frac{7}{3}\) / \(\frac{7}{3}\) or \(-\frac{7}{3}\). The roots are (5) and (2), so the sum is (7) and the difference can be \(\pm3\). Hence the value is \(\frac{7}{3}\) or \(-\frac{7}{3}\).
Exam Tip
मूल (5) और (2) हैं इसलिए योग (7) और अंतर \(\pm3\) हो सकता है। इसलिए मान \(\frac{7}{3}\) या \(-\frac{7}{3}\) है।
