यदि \(3x^2+2x+\lambda=0\) की जड़ें वास्तविक नहीं हैं, तो \(\lambda\) पर सही शर्त क्या है?
If the roots of \(3x^2+2x+\lambda=0\) are not real, what is the correct condition on \(\lambda\)?
Explanation opens after your attempt
Correct Answer
A. \(\lambda>\frac{1}{3}\)
Concept
For non-real roots, (D<0) is required. From \(4-12\lambda<0\), we get \(\lambda>\frac{1}{3}\).
Why this answer is correct
The correct answer is A. \(\lambda>\frac{1}{3}\). For non-real roots, (D<0) is required. From \(4-12\lambda<0\), we get \(\lambda>\frac{1}{3}\).
Exam Tip
वास्तविक नहीं होने के लिए (D<0) चाहिए। \(4-12\lambda<0\) से \(\lambda>\frac{1}{3}\) मिलता है।
