यदि \(x^2+tx+12=0\) के वास्तविक मूल नहीं हैं तो (t) के लिए सही शर्त क्या है?
If \(x^2+tx+12=0\) has no real roots, what is the correct condition for (t)?
Explanation opens after your attempt
Correct Answer
A. \(t^2<48\)
Concept
For no real roots, (D<0) is required. So \(t^2-48<0\), that is \(t^2<48\).
Why this answer is correct
The correct answer is A. \(t^2<48\). For no real roots, (D<0) is required. So \(t^2-48<0\), that is \(t^2<48\).
Exam Tip
वास्तविक मूल नहीं होने के लिए (D<0) होना चाहिए। इसलिए \(t^2-48<0\), अर्थात \(t^2<48\)।
