यदि \(x^2+qx+10=0\) के वास्तविक मूल नहीं हैं तो (q) के लिए सही शर्त क्या है?
If \(x^2+qx+10=0\) has no real roots, what is the correct condition for (q)?
Explanation opens after your attempt
A. \(q^2<40\)
Concept
For no real roots, (D<0) is needed. So \(q^2-40<0\), that is \(q^2<40\).
Why this answer is correct
The correct answer is A. \(q^2<40\). For no real roots, (D<0) is needed. So \(q^2-40<0\), that is \(q^2<40\).
Exam Tip
वास्तविक मूल नहीं होने के लिए (D<0) चाहिए। इसलिए \(q^2-40<0\), अर्थात \(q^2<40\)।
