यदि \(4x^2-13x+3=0\) के मूल \(\alpha,\beta\) हैं, तो (\(\alpha-\beta\)2) क्या होगा?
If \(\alpha,\beta\) are roots of \(4x^2-13x+3=0\), what is (\(\alpha-\beta\)2)?
Explanation opens after your attempt
A. \( \frac{121}{16}\)
Concept
(\(\alpha-\beta\)2=\(\alpha+\beta\)2-4\alpha\beta=\left\(\frac{13}{4}\right\)2-3=\frac{121}{16}). In exams, use this identity for the square of difference.
Why this answer is correct
The correct answer is A. \( \frac{121}{16}\). (\(\alpha-\beta\)2=\(\alpha+\beta\)2-4\alpha\beta=\left\(\frac{13}{4}\right\)2-3=\frac{121}{16}). In exams, use this identity for the square of difference.
Exam Tip
(\(\alpha-\beta\)2=\(\alpha+\beta\)2-4\alpha\beta=\left\(\frac{13}{4}\right\)2-3=\frac{121}{16}) है। परीक्षा में अंतर का वर्ग इस पहचान से निकालें।
