यदि \(x^2-7x+12=0\) की जड़ें \(\alpha,\beta\) हैं, तो \(\frac{\alpha+1}{\alpha-1}+\frac{\beta+1}{\beta-1}\) का मान क्या है?
If \(\alpha,\beta\) are the roots of \(x^2-7x+12=0\), what is \(\frac{\alpha+1}{\alpha-1}+\frac{\beta+1}{\beta-1}\)?
Explanation opens after your attempt
Correct Answer
C. \(\frac{11}{3}\)
Concept
The roots are (3) and (4). Direct substitution gives \(\frac{4}{2}+\frac{5}{3}=\frac{11}{3}\).
Why this answer is correct
The correct answer is C. \(\frac{11}{3}\). The roots are (3) and (4). Direct substitution gives \(\frac{4}{2}+\frac{5}{3}=\frac{11}{3}\).
Exam Tip
जड़ें (3) और (4) हैं। सीधे रखने पर \(\frac{4}{2}+\frac{5}{3}=\frac{11}{3}\) मिलता है।
