Hard Mathematics Quadratic Equations Class 10 Level 32

यदि \(x^2-11x+24=0\) के मूल \(\alpha\) और \(\beta\) हैं तो \(\frac{1}{\alpha+1}+\frac{1}{\beta+1}\) का मान क्या है?

If \(\alpha\) and \(\beta\) are roots of \(x^2-11x+24=0\), what is the value of \(\frac{1}{\alpha+1}+\frac{1}{\beta+1}\)?

Explanation opens after your attempt
Correct Answer

A. \(\frac{13}{36}\)

Step 1

Concept

Here \(\alpha+\beta=11\) and \(\alpha\beta=24\). The value is \(\frac{\alpha+\beta+2}{\alpha\beta+\alpha+\beta+1}=\frac{13}{36}\).

Step 2

Why this answer is correct

The correct answer is A. \(\frac{13}{36}\). Here \(\alpha+\beta=11\) and \(\alpha\beta=24\). The value is \(\frac{\alpha+\beta+2}{\alpha\beta+\alpha+\beta+1}=\frac{13}{36}\).

Step 3

Exam Tip

यहां \(\alpha+\beta=11\) और \(\alpha\beta=24\) है। मान \(\frac{\alpha+\beta+2}{\alpha\beta+\alpha+\beta+1}=\frac{13}{36}\) होगा।
