यदि विविक्तकर (D=-\(t^2+4\)) है, तो वास्तविक मूलों की संख्या क्या होगी?
If the discriminant is (D=-\(t^2+4\)), what will be the number of real roots?
Explanation opens after your attempt
A. (0)
Concept
For any real (t), \(t^2+4>0\), so (D<0). Hence the number of real roots is (0).
Why this answer is correct
The correct answer is A. (0). For any real (t), \(t^2+4>0\), so (D<0). Hence the number of real roots is (0).
Exam Tip
किसी भी वास्तविक (t) के लिए \(t^2+4>0\), इसलिए (D<0) है। अतः वास्तविक मूल (0) होंगे।
